Orchids are fascinating plants with flowers that appear in a myriad of colors, shapes, and patterns on plants with many different foliage types.
And luckily for those of us without the luxury of having a greenhouse in our backyards, there are many different types of orchids that can be grown as houseplants.
We’re going to get up close and personal with a mere handful of the many different types of orchids that exist in the world.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
You’ll learn about 23 different types of orchids – a small sampling from the more than 700 genera in the Orchidaceae family! – as well as particular species or hybrids from each genus that you may enjoy growing at home.
As you read through this guide, I’ll let you know what to expect in terms of the flowers and plant growth, as well as the basic cultural requirements for each of these selections.
Then you can narrow down your shortlist to the types whose light, humidity, and water needs are a great fit for both your care-taking style and the conditions available in your home.
Ready to find your orchid match? Here’s a quick peek at the varieties we’ll cover up ahead, organized alphabetically by genus name:
23 Orchids to Grow Indoors
One of the important features you’ll learn about each of these selections is whether they are considered warm, intermediate, or cool growers, giving you an indication as to what type of temperature ranges they will need to thrive.
Here’s a quick snapshot of the temperature needs for these different categories:
- Warm growers prefer daytime temperatures of 70 to 90°F, and 60 to 75°F at night.
- Intermediate growers need daytime temperatures of 65 to 80°F, with nighttime temperatures of 55 to 70°F.
- Cool growers thrive in daytime temperatures of 60 to 75°F, and a nighttime range of 50 to 65°F.
To learn more about these differences, as well as an overview of basic care requirements, be sure to read our complete guide to growing and caring for orchids.
And one more note before we get started: if botanical names for species are something you are no stranger to, but orchids are a topic you are just starting to explore, you’ll notice that the way species are abbreviated is a bit different for orchids, as well as the way hybrids are described.
To avoid confusion, common genus abbreviations here may include two or more letters rather than one.
And hybrid cultivar names include the species and genus followed by the hybrid name, and then the cultivar name in single quotes.
1. Brassavola
Brassavola is a genus that contains approximately 20 species. These are native to tropical areas of Central America, South America, and the West Indies.
Epiphytes and lithophytes, Brassavola species are sympodial, with cylindrical leaves and pseudobulbs, the latter of which help to store water.
These fleshy leaves tend to be long and tapering. They’re usually green and are sometimes speckled with red.
Brassavola plants have a pendant growth habit and produce blooms in shades of white and greenish white, a common feature of flowers pollinated at night by moths.
Blooms are showy with large, ruffled or lobed lips, blooming primarily during the summer, and they are fragrant at night.
Brassavolas require bright light and while this can be primarily indirect light, they will appreciate a few hours of direct sunlight each day.
These orchids are warm to intermediate growers and are much more tolerant of low humidity levels than most of our other selections, requiring levels of only 30 to 50 percent.
Specimens can be mounted, which is a common way to grow epiphytes. They can also be cultivated in baskets or in pots if the potting medium has excellent drainage.
Potted specimens need to dry out between waterings, while those in baskets or mounted are usually watered by soaking them for 15 minutes about once a week.
Brassavolas are easy-care houseplants, and it’s not hard to encourage these orchids to rebloom.
2. Brassia
Native to tropical areas in the Americas, the Brassia genus includes 68 species, most of which are epiphytes, with a few terrestrial species as well.
Also known as “spider orchids,” these sympodial species have flattened, green pseudobulbs which often have a reddish tint.
Leaves are yellowish green, and linear to oblong or strap-shaped, on plants that range in size from small to large.
They produce multiple fragrant blooms on arching spikes, usually in shades of green, yellow, or tan.
These flowers have thin, wispy petals, and depending on the species or hybrid, they vary in size, with some being quite large.
Brassias tend to bloom in spring or summer, and sometimes produce flowers more than once a year.
They are cool, intermediate, or warm growers depending on the species or hybrid and require humidity levels between 50 and 70 percent.
These orchids generally need bright, filtered light and can be grown in lightly shaded, south-facing windowsills.
Brassias can easily be grown by beginners and may be cultivated in pots filled with an orchid-growing medium or mounted.
For specimens in pots, water when the surface of the potting medium is dry to the touch – approximately once a week from spring through autumn, and less frequently during winter.
For mounted plants, they will likely need to be watered about every other day.
If you’re looking for a Brassia to start with, Brs. verrucosa is one species you may want to consider.
It bears sprays of 10 to 20 light green to yellow blooms speckled with reddish-brown flecks and its long, thin petals and sepals give the flowers a spider-like appearance.
Brs. verrucosa is an intermediate grower that requires low to medium light, and the fragrant, eight- to 10-inch flowers bloom between spring and fall, lasting up to eight weeks.
3. Bulbophyllum
Bulbophyllum is a very large genus, containing over 2,000 species of orchids that are native to tropical and subtropical areas in Asia, Oceania, Africa, and the Americas.
Though some are lithophytes, most Bulbophyllum species are epiphytes. They have pseudobulbs for storing water, and their slightly cupped leaves may be thin, leathery, or fleshy.
Bulbophyllum species have light green or medium green foliage, and this genus includes both evergreen and deciduous plants.
With so many different species, this genus displays a lot of diversity – some of its members have flowers easily recognizable as orchids, while others are surprisingly un-flowerlike in their appearance.
Plants range in size from very small to very large, and while many of these species have fragrant blooms, some have an unpleasant odor that is intended to attract their main pollinators – flies.
Most of these orchids are intermediate growers, though some are warm growers and others prefer cool conditions.
They thrive in moderate to bright indirect light.
Some species can be cultivated in shallow pots, while those with long rhizomes tend to fare better in baskets or mounted on slabs. Fast growers, the roots of these orchids can be difficult to contain.
Bulbophyllums require humidity in the 50 to 70 percent range and are quite thirsty, with mounted specimens usually requiring daily watering and potted ones a few times a week.
Some of them require a period of winter rest with either less water or none at all.
Bulbophyllums may be a bit tricky, so if you’re a newbie orchidophile, you may prefer some of the other, beginner-friendly genera recommended in this article instead.
For intermediate and advanced orchid fans, if you’re ready to give cultivating the surprising blossoms of bulbophyllums a go, Bulb. Frank Smith is a hybrid you might want to consider.
Bulb. Frank Smith is an interspecies cross of Bulb. lobbii and Bulb. carunculatum. It bears star-shaped blooms that have yellow sepals and petals tinged with orange, and a deep red, small, tongue-shaped lip.
You can find Bulb. Frank Smith plants in two-inch pots from Aloha Hawaii Orchids at Amazon.
4. Calanthe
Calanthe is a genus of mostly terrestrial species, which was expanded in 2020 to incorporate a few other re-classified genera, including the genus Phaius.
This genus now includes 275 sympodial species native to tropical and subtropical areas of Africa, Asia, the Americas, and Oceania.
These plants are divided into two types, deciduous and evergreen.
The evergreen calanthes have no pseudobulbs, while they are prominent in deciduous varieties. Both types produce large, pleated leaves.
Flower spikes typically appear in winter, with blooms in shades of white, orange, brown, yellow, pink, purple, or blueish purple, lasting a month or longer.
Depending on the species or hybrid, a calanthe can be a cool, intermediate, or warm grower. All will thrive with bright, indirect light.
Evergreen species require a consistently moist potting medium year-round while deciduous types should receive less water during winter dormancy, only enough to keep the pseudobulbs from shriveling.
Newbie orchid fanatics will no doubt have an easier time with an evergreen calanthe, before moving on to the more tricky deciduous types.
One to start with is Cal. tankervilleae, also known as the “greater swamp orchid.” This is an evergreen, terrestrial, warm growing species that flowers in spring or early summer.
The petals are white on the outside and brownish purple on the inside, surrounding a tubular purple lip.
5. Cattleya
In addition to natural hybrids and many horticultural hybrids, there are over 120 species in the Cattleya genus, originating primarily from South America.
Known for their use by florists as cut flowers and in corsages, cattleyas are epiphytic or lithophytic plants sympodial orchids that produce pseudobulbs.
Cattleya leaves are medium green, thick, leathery, and usually oblong. Plants typically reach up to two feet tall, with hybrids being more compact.
These can be divided into two different types – “unifoliate” species that have one leaf per pseudobulb and “bifoliate” species that have two.
Unifoliate cattleyas tend to produce flowers in shades of violet, lavender, or white, while bifoliate types usually feature blooms in mahogany, purple, green, yellow, or orange hues.
Cattleya blooms are typically fragrant, large, showy, and funnel shaped, with ruffled lips.
Cattleya orchids are primarily intermediate growers, with some species and hybrids considered warm growers.
The best general temperature range is 70 to 85°F during the day, with nights between 55 and 60°F. They can tolerate higher daytime temperatures when provided with some shade.
Cattleyas appreciate bright light and do well when they receive a few hours of direct sunlight in the morning or late afternoon, but not at midday.
A humidity range of 40 to 80 percent is ideal.
Cattleyas should be allowed to dry almost completely between watering. Young plants and mini varieties need to be watered more frequently than larger varieties or more mature specimens.
In addition, these orchids should be watered less during winter dormancy, otherwise their roots can rot.
Cattleyas can be cultivated in pots or baskets, or they can be mounted on wood or cork.
There are a wide range of cattleyas requiring different expertise levels for successful cultivation. In general, hybrids tend to do better as houseplants than species plants.
One cattleya cultivar you might want to start with is C. Potinara Chief ‘Sweet Orange.’
This compact grower produces fiery-colored, fragrant flowers, measuring three and a half inches wide.

6. Coelogyne
When many of us think of orchids, we imagine a flower spike graced with a single, striking, large bloom, or perhaps a few large flowers.
If that’s the case for you as well, some of the members of the Coelogyne genus (pronounced “see lodge eh nee”) will have you rethinking this common perception!
Many species in this genus make a big visual impression with trailing flower spikes thickly covered with clusters of small blooms, particularly those previously classified as Dendrochilum species.
Reclassified in 2021, those formerly known as dendrochilums are commonly called “golden chain orchids” or “fox brush orchids,” in reference to their dense flower sprays. Blooms tend to be white, tan, or green in color.
The Coelogyne genus contains over 595 species from India, New Guinea, and Southeast Asia.
These sympodial orchids are mostly epiphytes and feature oval pseudobulbs.
Most coelogynes are intermediate growers that thrive in medium to bright, indirect light. In summer their humidity needs are high – about 85 percent – while in winter humidity should be decreased to between 60 and 70 percent.
They should be watered when the potting medium starts to dry out, but before it has dried completely. These orchids also require a short winter rest period, with less frequent irrigation.
Coelogynes are grown in pots, and they are considered easy to cultivate, even for beginners.
If you’re looking for a starter plant, try Coel. wenzelii, an epiphyte that produces reddish-orange flowers in winter and thrives in warm conditions in low or medium, indirect light.
7. Cycnoches
Known as “swan orchids” in reference to the shapes of their flowers, the 33 species of the Cycnoches genus are native to Central and South America.
These sympodial plants produce conical or spindle shaped pseudobulbs. Plants maintain only three pseudobulbs at a time, with the oldest dying back when a new one is produced.
Swan orchids are deciduous, with thin, pleated leaves.
The leaves drop after flowering, leaving only the pseudobulbs, which makes a Cycnoches specimen look more like a cactus than what you might expect from an orchid.
Cycnoches produce pendulous sprays of flowers that are very fragrant and tend to come in shades of red, bronze, white, yellow, or green.
Blooms are usually produced in fall, with flower size varying depending on the species or hybrid.
Swan orchids should be treated as warm growers from spring through autumn and intermediates during winter.
Provide bright, indirect light, with some direct sun in the morning.
Since they are deciduous, cycnoches orchids have changing water needs throughout the year, requiring lots of water during the growing season, followed by a drier rest season.
Cycnoches thrive with humidity levels in the range of 50 to 70 percent, and can be cultivated in pots or mounted.
These deciduous orchids may be best reserved for intermediate and advanced hobbyists. When you’re ready, an excellent species to start with is Cyc. warscewiczii.
With upside-down, fragrant flowers, this species has greenish-yellow petals and sepals surrounding a white lip.
8. Cymbidium
Cymbidiums are native to tropical and subtropical areas of Asia and Australia, and are commonly known as “boat orchids” in reference to the shape of the flowers’ lip.
The Cymbidium genus contains approximately 85 species, consisting of sympodial epiphytes, lithophytes, and terrestrial species. There are also many hybrids, as well as some mini hybrids.
They produce grass-like or strap-shaped leaves that are medium green to golden green in color, which in most species are produced from elongated or oval-shaped pseudobulbs.
Plants can be compact or large, reaching up to three feet tall.
Blooms of this genus are diverse, with some producing small flowers, and others large ones.
Some blooms are scented, typically in shades of white, yellow, green, pink, and red.
Large-flowered types are cool growers, while small-flowered tropical and subtropical types prefer warm conditions.
There are also some small-flowered terrestrials from temperate climates that prefer cool, moist conditions.
Most cymbidiums can be treated as intermediate growers if you aren’t sure what type you have.
These plants thrive in bright, direct light and direct sun at midday should be avoided.
The growing medium should be kept moist, watering when the top inch or two is dry, and they like a humidity range of 40 to 70 percent.
While these orchids can be cultivated in pots, baskets tend to work better for specimens with trailing inflorescences.
Cymbidiums are good for beginners – and a good one to start with is Cym. Sarah Jane ‘Ice Cascade.’
This hybrid is a warm grower that doesn’t require cooler winter temperatures. Its white blooms appear in the summer or fall, last for around a month, and are very fragrant.
9. Dendrobium
Dendrobium is an extremely diverse genus containing at least 1,600 different species, whose native habitats range throughout Asia and Australia.
These sympodial orchids bear small or large blooms, with some lasting just a few days and others lasting for weeks, depending on the species or hybrid.
Some dendrobiums are suitable for beginner growers while others are best left to more advanced orchidophiles.
Native to a large variety of different habitats, it is impossible to succinctly generalize about either growth characteristics or care for plants in this genus.
For the purposes of this article, we will instead provide you with some appetite-whetting info on just one species that is easy to find and cultivate – Den. kingianum.
Den. kingianum is one of the most easy-care dendrobiums you can keep as a houseplant.
Also known as “pink rock orchid,” this lithophyte is highly adaptable to both chilly temperatures and extreme heat.
For best results, treat it like a cool grower, providing bright indirect light, at least 50 percent humidity, and water when the potting medium starts to dry out.
A cool period in late fall with reduced water will promote flower production.
There are many different forms and cultivars of this species, with flower colors in shades of white, pink, mauve, purple, and yellow. Blooms are long-lasting and fragrant on compact plants.
You can purchase Den. kingianum plants that are ready to bloom from Orchid Insanity via Amazon.
10. Encyclia
Encyclia orchids are epiphytes, with natural habitats that range from hot, dry areas to misty rainforests.
With approximately 171 species from Mexico, Central America, South America, and the West Indies, these range in size from just two inches to over two feet tall.
These sympodial plants produce fleshy, strap-like leaves from the pseudobulbs and bear flowers in shades of green, brown, maroon, or white.
Usually a dozen or more blooms are produced on each flower spike, with each individual flower measuring one to two inches wide.
Encyclias are mostly intermediate to warm growers, with some preferring cool conditions. They require good air circulation, and bright to very bright, filtered light.
These should be allowed to dry out between waterings. They need drier conditions in winter, but watering should be increased when plants are putting on new growth.
Encyclias require only moderate humidity of 40 to 70 percent, preferring slightly higher levels during the growing season than during winter.
These orchids can be cultivated in small clay or plastic pots, or can be mounted, and they are excellent for beginning growers.
E. cordigera is one you might choose to start with. It produces fragrant blooms that last for up to three months.
There are many different cultivars of E. cordigera, displaying combinations of dark mahogany petals and sepals with a white, pink, or purple lip.
11. Epidendrum
If it seemed like Dendrobiums were a diverse bunch, meet Epidendrum, a genus that includes over 1,700 species.
Also called “crucifix orchids,” this extremely varied genus includes species native to Central America, Mexico, South America, and the United States.
These sympodial plants are epiphytic or terrestrial, and the genus Epidendrum includes both miniature species and giants that reach six feet tall, as well as many sizes in between.
Most epidendrums produce cane-like pseudobulbs or reedlike stems.
Although blooms are long-lasting and often red, magenta, orange, or green, these may bear flowers in all colors of the spectrum except for black and cyan blue.
Most epidendrums prefer intermediate temperatures, while others prefer cool or warm conditions, depending on the species.
They require bright light, a humidity range of 50 to 80 percent, and should be allowed to dry out completely between waterings.
Epidendrums are evergreen and continue growing throughout the year, but some do prefer a rest period with cooler, drier conditions in the winter.
Crucifix orchids can be cultivated in pots filled with a coarse potting medium and smaller specimens can also be mounted.
Raising epidendrums is straightforward enough for even beginning orchid growers.
Since your choices are numerous, here’s a suggestion to start with: Also known as “fire star orchid” or “poor man’s orchid,” Epi. radicans is a type of terrestrial orchid that has reedlike stems and fiery, dark reddish-orange and yellow blooms.
Epi. radicans prefers warm temperatures, and should be watered approximately once a week.
You can purchase Epi. radicans orchids in four-inch pots from the Emerald Goddess Gardens Store via Amazon.
12. Laelia
The Laelia genus is made up of 24 species from Mexico, the West Indies, and Central and South America.
These sympodial epiphytic and lithophytic plants feature pseudobulbs and leathery or fleshy leaves, which sometimes have a purplish tint.
Laelias feature star-shaped blooms and bold colors, though white and purple flowers are the most common.
Species in this genus are mostly considered intermediate growers, but cultural conditions vary between different types.
In general, these orchids require moderate to bright light, ample water during the growing season, and slightly drier conditions during winter dormancy.
Plants should be allowed to dry out between waterings, and should be kept slightly drier after flowering. Provide 50 to 70 percent humidity.
Most laelias flourish in pots, though some are best cultivated in baskets.
L. purpurata var. striata ‘Stars and Bars‘ x var. flamea produces clusters of three to five large flowers that are white with a bright, pinkish-purple lip and pink striping on the petals and sepals.
The flowers are five to seven inches wide, and bloom in spring or summer.
You can purchase L. purpurata var. striata ‘Stars and Bars‘ x var. flamea hybrid plants in four-inch pots from Aloha Hawaii Orchids via Amazon.
13. Ludisia
Commonly called “jewel orchids,” members of the Ludisia genus are grown primarily for their beautifully patterned foliage rather than their flowers.
This genus contains only two species, Lus. discolor, which is native to China, Indonesia, and other parts of Southeast Asia, and Lus. ravinii, native to the Philippines.
These terrestrial or lithophytic plants are sympodial and have oval-shaped leaves that are dark green to brownish-purple with contrasting, gold to red-colored veins.
Plants reach about 10 inches tall including their inflorescences, which hold small, faintly scented, white or pink flowers.
Flower spikes can be either upright or trailing, usually producing blooms during the winter months.
Jewel orchids can be cared for much like African violets, making them easy to keep as houseplants, even for beginners.
The plants are intermediate growers. They can be cultivated in medium, indirect light, and are easy to water since they have the same requirements throughout the year.
Keep the potting medium evenly moist, never allowing the soil to dry out all the way as they don’t have pseudobulbs to store moisture.
Ideal humidity for these orchids is in the 40 to 80 percent range, though with higher humidity, increased air flow is important.
Since they have a creeping growth habit, cultivate them in wide, shallow pots.
Lus. discolor is the species you’re most likely to find to cultivate as a houseplant.
14. Miltonia
With star-shaped blooms, miltonias hail from South America, primarily from Brazil.
The genus counts just 12 species and four natural hybrids, but there are many interspecies and intergeneric Miltonia hybrids as well.
Miltonia species are sympodial and produce pseudobulbs on creeping rhizomes with linear or strap-shaped leaves that are creased in the middle.
These epiphytic plants reach approximately 20 inches tall, and feature spikes of one to 12 flowers. The flowers tend to have pointy petals and sepals surrounding a large lip.
These warm growing orchids require bright light and humidity in the range of 60 to 75 percent. Their leaves will develop accordion-like folds when humidity is too low.
Miltonias need plenty of water during the growing season, and less while resting. They should be allowed to dry out almost entirely between watering.
They are beginner-friendly and can be cultivated in wide shallow pots, baskets, or on mounts.
Milt. spectabilis is a good species to start with, and is available in many lovely varieties and crosses from nurseries.
15. Oncidium
Commonly known as “dancing lady orchids,” oncidiums produce light and airy sprays of warm-toned flowers.
The Oncidium genus contains over 330 species from Florida, Mexico, Central America, South America, and the West Indies. These originate in diverse habitats, though most are tropical or subtropical.
Oncidiums are sympodial and have water-retentive pseudobulbs. Some types have fleshy, water-storing leaves, while others have thin ones.
The blooms are in shades of yellow, brown, and maroon, and frequently have spots or splotches.
Since this is a diverse genus, growing requirements will vary from species to species and hybrid to hybrid.
Oncidiums are considered to be intermediate to warm growers, and require bright light, preferably with at least an hour of direct sunlight per day. Thick-leaved oncidiums can tolerate more direct sun.
Species with thin leaves require more frequent watering than those with fleshy ones. In general, the potting medium should be allowed to dry about halfway between waterings.
Some species have a winter rest period, at which time they should be watered less frequently than during the growing season.
Humidity should be between 30 and 80 percent. Watch for accordion folds in leaves as a sign that more humidity is needed.
Species that are more drought tolerant can be mounted, while those cultivated in pots should be kept in small-sized pots to discourage root rot.
Oncidiums tend to be easy to care for, even for beginning orchidophiles.
To get started with plants in this genus, you might consider Onc. Rex’s Luck ‘Firefly,’ a slightly fragrant hybrid that has curled or wavy, purple and white petals and sepals, graced with a bright yellow spot on its maroon lip.
You can purchase a live Onc. Rex’s Luck ‘Firefly’ in a three-and-a-half-inch pot from Orchid Insanity via Amazon. These specimens are shipped 12 to 18 months from blooming.
16. Paphiopedilum
Paphiopedilums, called “paphs” for short, are mesmerizing orchids to behold.
To quote William Cullina, author of “Understanding Orchids,” available at Amazon, paphiopedilums “look as if they have been assembled by someone with an eccentric bent and a good eye for proportion and balance.”
I agree wholeheartedly with Cullina’s description of these astonishing flowers.
Native to tropical areas of Asia, the Paphiopedilum genus contains over 100 species. Many hybrids have been produced as well.
Also called “Venus slippers,” “lady slippers,” or “slipper orchids” in reference to the shape of the flower’s lip, paphiopedilums are usually terrestrial, but sometimes live on rocks or trees.
They are sympodial, but have no pseudobulbs, and produce a fan of three to eight leaves, which are usually short and strap shaped.
These leaves are either solid green or mottled dark and light green, and sometimes have purple undersides.
These plants tend to reach up to two feet tall, including their inflorescences.
One or more large showy blooms are produced per spike, appearing in shades of green, pink, burgundy, yellow, ivory, or umber.
Flowers often have lines, spots, and veining on the petals, sepals, and lips.
Paphs with solid green leaves and one bloom per spike are temperate growers, while those that have mottled leaves, or solid green leaves with multiple blooms, are warm growers.
They don’t require as much light as some orchids – only medium, indirect light is needed, making them good companions for prayer plants.
Since paphiopedilums don’t have water-storing pseudobulbs, they mustn’t be allowed to dry out.
The potting medium should be kept moist but not soggy, and should be watered when the surface is dry to the touch.
Lady slippers need at least 50 percent humidity, should be cultivated in plastic or clay pots, and need to be repotted yearly.
Some paphiopedilums are easy to cultivate for beginners, while others are better left to intermediate or advanced orchidophiles.
If you’re just getting started, choose a mottled leaf species or hybrid, such as Paph. callosum, which will make a good houseplant.
Its blooms may be red, pink, green, white, or wine-colored.
17. Phalaenopsis
Phalaenopsis orchids are known as being the easiest orchids to grow, as well as the easiest to find – you may even be able to pick one up in your local supermarket!
Native to tropical and subtropical areas of Asia and Australia, the Phalaenopsis genus contains approximately 78 species, plus natural and horticultural hybrids.
Also known as “moth orchids,” these species are mostly epiphytic, though some are lithophytes or terrestrials.
“Phals,” as they are affectionately called, are monopodial with large, fleshy leaves which help to store water. The tops of the leaves are medium to dark green, and the bottoms may be maroon.
These plants can reach up to three feet tall when you include their arching flower spikes.
Large blooms open in late winter to spring, and are typically colored in shades of white, yellow, pink, peach, or purple. These gorgeous flowers last many months, and some are fragrant.
Phals are easy to cultivate in average household conditions, and are considered intermediate to warm growers.
They are also fairly flexible – provide them with low, medium, or bright indirect light.
Keep the potting medium slightly damp, allowing it to almost dry between waterings, and provide humidity between 40 and 80 percent.
Because of their photosynthetic roots, phals are often cultivated in clear plastic pots, but they can also be grown in baskets.
For more tips on caring for these stunning houseplants, check out our guide to growing and caring for Phalaenopsis orchids.
18. Phragmipedium
Those who enjoy the challenge of growing moisture-loving carnivorous plants will be thrilled with this next selection.
Members of the Phragmipedium genus are, like paphiopedilums, also called “slipper orchids.”
The 20 or so species in this genus are terrestrials, lithophytes, or epiphytes and hail from Mexico, Central America, and South America.
These sympodial plants have narrow leaves arranged like a fan, and fibrous roots.
With a pouch- or slipper-shaped lip, a Phragmipedium flower looks quite similar to that of a Paphiopedilum.
Often casually called “phrags,” their blooms can be green, greenish-yellow, maroon, red, orange, or bright pink.
Along with their slipper-shaped lips, phragmipediums sometimes have narrow, twisted sepals and petals.
In some species and hybrids, these can reach astonishing lengths, giving the blooms a truly unique appearance.
Phragmipediums are warm to intermediate growers and require bright, indirect light.
Intermediate and advanced orchid enthusiasts will be the most successful growing phragmipediums, as they have very specific moisture requirements.
Most species require a damp potting medium, and some are even grown with their pots sitting in saucers of water – a condition which would put many houseplants on the express train straight to Root Rot Central.
In addition to these particular hydration needs, these orchids also require filtered, distilled, or rainwater that has not been chemically treated, and humidity between 60 and 70 percent.
If the fascinating flowers of these moisture-loving orchids fill you with deep admiration, Phrag. caudatum is an excellent species to start with.
Phrag. caudatum tolerates warmer temperatures and is not as thirsty as its relatives, making it one of the more accessible phragmipediums to grow.
The long petals and sepals are pale greenish-yellow with a darker greenish-yellow pattern that might remind you of crackled porcelain, surrounding a ruddy, pouch-shaped lip.
19. Polystachya
Polystachya is a genus composed mostly of epiphytes, with some lithophytes, and more rarely, terrestrials.
With over 240 species, the members of this genus are native to tropical and subtropical habitats in Africa, the Americas, and Asia.
Also called “yellowspike orchids,” these small to medium-sized, compact plants are sympodial and produce pseudobulbs or reedlike stems topped with leathery, fleshy leaves. Some species are deciduous.
These plants produce spikes with many small, fragrant flowers, usually in shades of yellow, orange, white, or green. Their inflorescences last one month or longer, with some species blooming on and off throughout the year.
The flowers of these plants are non-resupinate, meaning the lip of the flower is on the top rather than the bottom, making them look as if they’re upside down compared to other orchids such as phals and oncidiums.
Most polystachyas are warm to intermediate growers and require bright to very bright light.
Those with prominent pseudobulbs have a greater water storage capacity and can go longer without water than those with reedlike stems.
While it’s best to check the moisture needs of your particular hybrid or species, as a general rule, it’s best to wait until the substrate has almost dried out before watering it.
Those that are deciduous should be watered amply during their period of active growth, but should receive a rest period (while leaves are gone) with little or no water, depending on the species.
Provide polystachyas with a humidity level of 40 to 60 percent, and cultivate them in pots or on mounts.
Beginners can easily grow evergreen polystachyas, but may want to avoid deciduous species until they’ve gained more experience.
A great starter species, Pol. bella bears small, fragrant, yellow flowers. This evergreen species is an intermediate to cool grower.
20. Prosthechea
With over 120 sympodial species, the Prosthechea genus is native to tropical zones of the Americas.
Epiphytes with elongated pseudobulbs and narrow, strap-shaped leaves, plants in this genus can be divided into two groups.
The cockleshell group has flowers that seem to be upside down, since their lips are on the tops of the blooms. The other unnamed group has lips on the bottom, and have more brightly-colored blooms.
The long-lasting, highly fragrant flowers typically bloom in winter and some have a bloom period that extends into the spring or beyond.
In fact, Psh. cochleata, the “clamshell” or “cockleshell” orchid, has sequentially blooming inflorescences that can remain in flower for 12 to 18 months.
Prosthetcheas are intermediate growers, but they can tolerate higher temperatures well.
They should be grown in bright indirect light, with good air circulation and moderate to high humidity, between 40 and 85 percent.
While the growing medium of cockleshell types should be kept moist (but not soggy) for most of the year, plants in the other group should be given a drier rest period during the winter.
Cockleshells should be cultivated in baskets filled with moss or bark, and the others can be grown on mounts, in baskets, or in pots. Both types are considered great options for the beginner enthusiast.
Psh. radiata, formerly classified as Encyclia radiata, is an excellent choice for a starter plant.
It is a fast grower that bears coconut-scented blooms in the spring. The flowers are cream colored with an upside-down lip that is striped with purple.
You can find Psh. radiata orchids in four-inch pots from Aloha Hawaii Orchids via Amazon.
21. Rhynchostylis
Known as “foxtail orchids,” there are only five species in the Rhynchostylis genus, and they all hail from Asia.
These tropical orchids are epiphytic or lithophytic, exhibit monopodial growth, and have fleshy, leathery, strap-shaped leaves.
The flower sprays are arching or pendant and bear showy, highly fragrant blooms in shades of white to magenta, often with bold red or purple spots.
These intermediate to warm growers require bright, indirect light with humidity around 75 percent, and should be watered daily if grown in baskets or mounted.
For specimens cultivated in pots, water when the medium has just started to dry out. The exception to this is when they are in flower, at which time the growing medium should be kept moist.
These orchids need a drier rest period outside of the growing season, and are traditionally grown in hanging baskets or mounted.
Because of their somewhat involved cultural requirements, beginning growers may want to hold off on experimenting with these until they have gained more experience with the orchid family.
22. Vanda
While I promised you a list of orchids you can grow indoors as houseplants, Vandas are much better suited to being cultivated in greenhouses.
But any respectable list of popular orchid selections would be lacking if it didn’t include this member of the family!
Hailing primarily from low-altitude areas in the subtropics and tropics, the Vanda genus consists of 85 species native to Australia and Asia.
These monopodial orchids have large, aerial roots and grow on trees or rocks in the wild. Typically tall plants with the largest species reaching six feet in height, some grow to only a few inches.
Leaf type varies among vandas. Some are strap shaped and leathery, others have terete (pencil-shaped) leaves, and some have semi-terete leaves. In general, the foliage has a medium green hue.
Blooms are usually large and showy, ranging from one to six inches wide, appearing in a vast array of colors and sometimes featuring a checkerboard or mosaic pattern, or spots.
Vandas can bloom at any time of the year, with flowers that can last anywhere from a couple of weeks to a couple of months, and some are fragrant.
At their best when grown in greenhouse conditions, you may be able to cultivate them successfully as houseplants if you can replicate the intense light and high humidity more typical of a greenhouse.
Most vandas are intermediate to warm growers, and they can tolerate daytime temperatures up to 95°F.
They need bright, intense light. Those with pencil-shaped leaves need up to six hours a day of direct sun, while those with strap-shaped leaves should not receive direct sun at midday.
Vandas tend to grow poorly in pots and so are usually placed in slatted baskets where the roots will live in airy conditions and the bloom spikes can trail down.
They will need to be watered or misted often, and grow best in 80 percent humidity.
Watering several times each day may be required in warm weather, but irrigation should be less frequent when conditions are cooler.

23. Zygopetalum
Native to South America, the 15 or 16 members of the Zygopetalum genus are large, sympodial epiphytes or terrestrial plants.
They produce pseudobulbs with fans of light green strap-shaped leaves with lighter veining.
The blooms range in size from small to large and are usually green with maroon patterns, and a large lip in a contrasting color.
Flowers are fleshy, frequently featuring leopard-like spots, and bloom in winter or early spring, lasting for two to three months. Some of them are fragrant.
Zygopetalums are intermediate growers and they prefer bright indirect light, though some direct sunlight is fine early in the morning or late in the day.
Humidity should be at least 50 percent and the potting medium should be kept slightly damp. They need plenty of water while actively growing, less while at rest.
Zygopetalum orchids will need fairly large pots to contain their large root systems.
These plants are fairly straightforward to take care of, making them suitable for beginners.
