Garden pinks are an old-fashioned favorite beloved for the sweetly spicy fragrance and charming, frilled flowers in shades of pink, red, and white.
With all the appeal of their larger cousin, the carnation, pinks are easily grown, have a full flowering season, and are among the best scented perennials in the garden.
And they’re an absolute must-have if you enjoy bouquets of freshly cut flowers!
Here are all the details you’ll need to grow pretty garden pinks yourself.
What You Will Learn
Cultivation and History
Dianthus is a large genus in the family Caryophyllaceae, with over 300 species endemic to Asia, Europe, and Japan plus a North American alpine species. The genus name is derived from the Greek words dios (god) and anthos (flower), meaning “divine flower” or “flower of the gods.”
Garden pinks or Dianthus plumarius is a species within the Dianthus genus and includes many cultivars that are grown in gardens and are suitable for landscape applications.
D. plumarius are also called common, cottage, Scotch, or wild pinks, and are native to central Europe, being introduced to the UK around the year 1100.
A short-lived perennial evergreen, it has a mat-forming growth habit reaching 1- 2 feet tall and is hardy in Zones 4-9. Simple lancet leaves grow opposite one another on upright, branching stems in a subdued shade of glaucous gray green.
The pretty flowers grow in scapes of 3 to 5 buds and can be single, semi-double, or double petaled ranging in size from 1 to 2.5 inches – with the doubles typically offering the largest blooms.
They come in tones of maroon, mauve, purple, pink, red, and white and have a seemingly infinite variety of color patterns, often with a striking eye of contrasting color.
Blooming from May to July, plumarius will re-bloom lightly after the first flush.
Grown for their pretty, fringed flowers with a spicy fragrance of cloves, they’ve been cultivated for centuries.
Numerous references to their popularity are found in European art works, tapestries, and the illuminated illustrations of Medieval texts and prayer books.
And petals of D. plumarius were once added to wines and cordials to lend a spicy flavor – one of the oldest known cultivars is actually called ‘Sops in Wine’!
Naming of the species is a little unclear. Some believe it comes from the German name for plants that bloomed at Pentecost called pfingsten. Others say it comes from the jagged petal edges, which look as though cut by pinking shears.
Regardless of the name origin, the color is named for the flower, and not the other way around. Until the eighteenth century, flowers in this shade were referred to as blush, carnation, flesh-colored, light or pale red, or rose, but never as “pink”.
Garden pinks can be propagated by seed or by cuttings.
To grow from seed, start seeds indoors 6 to 8 weeks before the last frost in your region.
- Use a light starter soil in trays and keep it moist throughout the germination and indoor growth periods.
- Scatter seeds lightly and cover with 1/4 inch of soil.
- Place in a warm location – the ideal temperature for germination is 60 to 70 degrees F.
- Seeds germinate and sprout in 8 to 10 days.
- After a few weeks, plants will form a good root system and can be potted up or transplanted outdoors.
Many cultivars are sterile and must be propagated by cuttings to ensure the same characteristics of the parent plant.
This can be done with non-flowering cuttings taken in the summer.
- Cut shoots 2 to 3 inches long, just below a leaf node.
- Remove any lower leaves close to the stem.
- Dip the bottom 1 inch in a rooting compound.
- Insert cuttings into 4 or 6-inch pots filled with moist rooting soil – 50 percent compost or peat and 50 percent sharp, horticultural sand.
- If the air is dry, cover with a cloche or propagator lid but ensure the lid is propped up for proper air circulation – dianthus is averse to being too closely covered.
- Place pots in bright, indirect sunlight and keep the soil moist.
- Transplant in early fall when new roots are established for blooms the following year.
How to Grow
Add 4 to 6 inches of well-rotted manure or compost to enrich the soil before planting, and ensure the site is well-draining. Standing water in winter can be a problem and they need excellent drainage to prevent dieback. Add sharp sand to the planting site to improve drainage if needed.
They require dry to medium moisture levels and full sun for a minimum of six hours per day – although they’ll appreciate some afternoon shade in very hot summer weather. And they can tolerate humidity, but ensure plants have proper air circulation to prevent fungal infections.
Although perennial, they are short lived and will form bare patches in the center where the plant dies off. Plan on renewing them every 3 to 4 years.
Because they’re so easy to propagate, starting a few cuttings each year is a good way to ensure your plants always survive the winter.
D. plumarius also benefits from deadheading spent flowers which will encourage a second, lighter flush of blooms.
In the garden, plants can be spaced 9 to 12 inches apart. In containers they can be closer, about 6 to 9 inches apart.
- Hardy in Zones 3-9, D. plumarius will appreciate a thick mulch in winter to protect it from cold and harsh winds.
- In colder regions, they can easily be grown from seed as an annual if started early indoors.
- Pinks have a sweet fragrance of cloves and make a wonderful, long-lasting cut flower – be sure to plant plenty to cut for indoor arrangements.
- Old-fashioned varieties will self-seed readily in optimum conditions – leave some seedheads in place if so desired.
- Replace every 3 to 4 years to keep plants looking vibrant.
- Plants are deer resistant.
Pruning and Maintenance
Garden pinks are easy to care for and will respond well to just a little TLC.
Prompt deadheading of spent flowers will extend the bloom period and encourage new buds. For large plantings, shear the plants after blooming. This prevents self-seeding, trims the stems and foliage, and encourages a second, lighter flush of flowers.
In regions with cold winters, provide a 4 to 6-inch layer of dry mulch such as hay, shredded leaves, or straw.
In spring, once new foliage begins to emerge but before the flower buds, remove any mulch or winter debris.
Remove any dead spots that developed over winter, then top and side dress plants with organic material such as aged compost or manure. Fluff the material before top dressing and rake material gently down to the roots.
Cultivars to Select
A dwarf plumarius, ‘Sweetness’ blooms in a pretty mix of single flowers in shades of pink, rose, and white with and without contrasting eyes. This Fleuroselect award winner is beloved for their masses of first-year flowers that bloom from July to September with early indoor sowing.

Attracts bees and butterflies but repels deer and rabbits. ‘Sonata’ mixed seeds can be purchased from Astor Farm on Amazon.
There are other species of dianthus often referred to as garden pinks, due to their many similarities.
The most common of these are:
- Cheddar Pinks, D. gratianopolitanus
- China Pinks, D. chinensis
- Sweet William, D. barbatus
Cheddar Pinks, D. gratianopolitanus
D. gratianopolitanus, or Cheddar pinks, are native to western and central Europe, and have a tufted, mounding form with small, fringed flowers in mauve, pink, and rose with a rich, spicy perfume.
They flower abundantly in spring and early summer with a second, lighter, bloom after the first flush if spent flowers are deadheaded.
Growing 5 to 6 inches tall with a spread of 10 to 12 inches, Cheddars are hardy in Zones 4-8.
China Pinks, D. chinensis
D. chinensis are commonly called China or rainbow pinks, and are native to east Asia including China, Korea, Mongolia, and southeast Russia. Extensively hybridized, they’re found in most garden shops.
Plants and can grow as tall as 30 inches, although many cultivars are bred for compact or mid-sized growth with a mature height of 6 to 12 and 12 to 18 inches.
They feature fragrant flower clusters in shades of mauve, pink, red, and white with numerous bicolors and pattern variety. Blooming in summer, many will repeat with a vigorous pruning after the first flush of flowers.
They prefer cool summers and dislike in heat and humidity. Grown as a biennial or short-lived perennial, they’re hardy in Zones 6-9.
Sweet William, D. barbatus
Commonly called sweet William, D. barbatus is another popular garden species. They can grow as tall as 36 inches, but typical growth is 12 to 24 inches with many cultivars bred as dwarf plants 6 to 8 inches tall.
They feature full, terminal clusters of small single, semi, or double flowers 3 to 5 inches wide in vivid, patterned shades of bubblegum, mauve, red, and white plus bicolors and often with a contrasting eye. Old fashioned varieties are fragrant, but many of the newer cultivars are scent-free.
Winter hardy in Zones 3-9, sweet Williams are grown as a biennial or short-lived perennial that re-seeds readily, remaining vibrant in the garden for years. When grown from seed, they’ll bloom the first year if started early indoors.
Grow sweet William’s as for d. plumarius, providing some light afternoon shade in areas with hot summers.
Managing Pests and Problems
In areas with warm, humid summers or prolonged wet spells, leaf spot bacteria, Alternaria solani and Septoria lycopersici, can cause blight – brown, gray, tan, or yellow spots that first appear on foliage.
Remove infected foliage and ensure plants are spaced for adequate air circulation and use a multipurpose antifungal spray to treat plants. Bonide Fung-Onil Fungicide controls numerous common diseases and is available on Amazon.
Spider mites and aphids like to suck sap from dianthus and can be controlled with a good blast from the garden hose. Make sure to spray the underside of leaves to get all of them. Or, an insecticidal soap will dispatch most insects, as will a spray of neem oil. Adding ladybugs to the garden is another good way of controlling the smaller pest insects.
Crown rot can also be a problem that shows up as wilt and dieback, and prevention is the best solution. Ensure your plants have excellent drainage, particularly in winter when standing water can cause damage.
Thankfully, slugs, snails, and deer all find dianthus distasteful!

Best Uses in the Garden
Compact or dwarf plants with a low-growing habit are best suited to the front of beds or borders, containers, edging, rockeries, and windowboxes. And they make a cheery, mat-forming ground cover in sunny spots.
Mid-sized and tall plants are well-suited to the middle of beds and borders, alongside paths, and close to terraces, patios, and open windows where their lovely perfume can be enjoyed.
And, they’re a natural in the cutting garden of course! Dianthus are an excellent, long-lasting cut flower – so plant plenty of the mid and tall-stemmed varieties to bring inside for arrangements.
Now that you’ve been tickled pink, think you might give these old-time lovelies a try?
Compact, mid, or full-sized, there’s a cultivar waiting to add color and fragrance to your garden – and remember to plant some for cutting!
