Before we get too far into this, I have a confession:
I love marigolds, everything about them.
So, if you were expecting an article about these annual flowers that’s written with journalistic detachment, you’re out of luck. This is my tribute to the peerless marigold, recognizing its great virtues and its hangups as well, with unabashed affection.
While preparing for this article, I learned quite a few interesting things about these flowers. They are a surprisingly far-flung flower that has traveled across the Atlantic on multiple occasions. One variety of the flower is even fed to chickens so that egg yolks have a more perfect yellow color.
They might be a familiar sight, but marigolds have a few tricks available to them that can surprise even the most educated gardener. Grab your coffee or your tea, because we’re headed to marigold town!
(That sounded a lot better in my head…)
Back and Forth Across the Atlantic
I read a nice apocryphal tale about the origin of the flower’s name.
The version of the story I read indicated that Mother Mary of the Christian tradition was robbed by bandits, but when they cut open her purse all that fell out were yellow flowers, something that would one day by named “marigold” (Mary’s gold) in her honor.
But there’s a little hole in that story – and I’m not just talking about the one in the purse.
The varieties we’re discussing today are botanically known as Tagetes and are indigenous to the Americas. Discovered in the 1500s in Central and South America, these flowers had great religious and social importance to the native peoples of the Americas, and they eventually crossed the Atlantic to Europe.
Here, the story of Tagetes takes both directions at a fork in the road.
Tagetes erecta, commonly known as the African marigold, made its way to France and North Africa. After a considerable length of time, the flowers naturalized to the environment of North Africa so that when European settlers visited the region, they assumed the flowers were African in origin.
The French marigold, or Tagetes patula, had a similar journey. Their seeds crossed the ocean from the Americas with European explorers who were returning home. T. patula made its home in France and became a popular flower in the region, earning its common name.
Both species then made another journey across the Atlantic and returned home to the Americas before becoming a popular and standard choice for North American gardeners.
So what about that whole Mother Mary story? How could these flowers be something referenced in biblical tales if the Americas weren’t even discovered yet? Don’t worry, I did some digging on that, too.
It seems that the European-originated species Calendula was likely the flower referenced here. Some species, such as Calendula officinalis, share similarities with our friend Tagetes, and even have a common nickname of marigold. In this case it is the pot marigold more specifically, and they were likely the flowers referenced in this tale.
That was a fun line of questioning that led me down the marigold rabbit hole, but you’re probably ready to learn about generalized care for these classic flowers. Shall we?
There’s a reason people have used these flowers as a garden staple for a very long time. Tolerant of heat, drought, and pests, the marigold is about as easy to care for as they come.
They take off easily from seed, either grown indoors during the winter months or sown directly into the soil when it’s warmer out.
You can plant them in almost any area that receives sufficient sun, and are an ideal choice when you’re planting with style. Marigolds are one of the best choices to use when you’re a free-spirited gardener who wants their plants to be happy.
Better yet, Tagetes offers a slew of benefits for the rest of your garden. From deterring pests to attracting pollinators and desirable insects, and improving the soil quality, marigolds should find their way into your garden every year.
Gimme a Drink!
In my book, the sign of a good flower is one that doesn’t require attentive watering. Tagetes fits this requirement pretty darn well.
When first planting these guys, it’s best soak the soil thoroughly. This is standard practice with most plantings. Not only does it give the plant a nice drink to get started growing in its new home, it also helps to settle the freshly disturbed soil.
Established plants don’t need much in the way of watering. In fact, unless the weather is unusually dry and hot, they don’t need anything besides a good soaking once a week. Rainfall is often enough for these tough flowers.
Plants grown in containers are similarly tolerant of drought and only need to be watered when the top few inches of soil become dry to the touch. If the leaves start drooping, they’re in need of a drink sooner than later!
Be mindful not to water marigolds from the top. If their blooms get too wet, they will often turn into a mushy brown mess. Marigolds can be susceptible to root rot as well, if they are over watered.
Gimme Some Sun!
Native to sunny and warm climates, Tagetes prefer brightly sunny areas with moderately-rich soil. They can withstand full sun exposure with impressive grace and only begin to show signs of stress when the weather is relentlessly hot, be it humid or dry.
Although capable of growing in a part-sun environment, marigolds will never shine in these conditions. In addition to developing weaker and less prolific blooms, when grown in the shade, they become susceptible to powdery mildew and a host of rots that affect buds and stems.
If you’ve got marigolds in a container, consider moving the pots to provide a few hours of cover from the sun during the hottest periods of the summer. It isn’t necessary, but they’ll be happier for it.
Keep a diligent eye out for spider mites when the weather is hot and dry, and look for little weblike buildups on plants to indicate their presence.
Like many plants, marigolds are also susceptible to yellow aster. Unfortunately, there isn’t much you can do if you find this nasty ailment in your garden except to dispose of infected plants.
Gimme Some Friends!
It’s difficult to find places where Tagetes is unwelcome.
The flower’s scent seems to deter nasty bugs and pests that would otherwise be ready to start munching down on your other tasty plants that are growing in the garden. Additionally, the roots have been shown to deter nematodes for up to a year.
I’ve seen other gardeners plant them when rotating their crops, to ensure healthier soil.
Ideal as a companion plant, the marigold often is planted as a border or buffer around a garden, since the pungent scent is so offensive to pests. From yours truly over here, I think marigolds smell like summer, but to each their own.
Tomatoes get along especially well with them. Try combining marigolds, tomatoes, basil, and alyssum in a planting. It looks nice and the plants seem to enjoy teaming up together. There’s enough variety in these choices to make some pretty stunning and edible combinations.
Just make sure you refer to it as “Mad Man Matt’s Plantastic Arrangement” when your family and friends ask about it.
Gimme Some Choices! (Where to Buy)
Because they have rightly earned their place as a garden favorite, we are able to choose from a great variety of marigolds to fit your needs. We’ll look at a few favorites for you to pick through here:
The African (or American) Variety
Reaching heights of up to 4 or 5 feet and topped with massive pom-pom flower heads, Tagetes erecta can be a bit of a bully in some plantings. It wants to grow wildly and will knock over other plants to achieve this. T. erecta can be especially demanding of space in containers.
Still, it’s my favorite variant. The giant blooms are a sampling of delightful and cheery yellows and oranges that look like they’re straight from a big ol’ box of Crayola crayons. They might require staking if they get too tall, but that’s alright. You can always spot my home by the wall of marigolds I’ve got growing in the front yard.
Moonsong Deep Orange has a deeply saturated color to its bloom that borders on the profuse.

I like this variety because it exhibits a restrained and rich color that nicely accents the other brighter shades of different cultivars. This type will grow to be about a foot high and about a foot wide.
Vanilla is my go-to choice when I want a white colored flower that pairs well with zinnias. I’ve got a major soft spot for white and yellow flowers, and the delightfully creamy texture of this one finds me ordering seeds on a regular basis.

This variety will grow to reach about eighteen inches in height and sheds water from its flowerheads more easily than other African marigolds.
Antigua is a must in any discussion of this flower. Easy-to-grow and providing a nice range of colors, the Antigua series is probably what comes to mind when people imagine these blooms.

Expect tons of flowers and a height reaching between one and two feet.
The French Type
With a daintier and more compact flower, Tagetes patula has the added benefit of possessing multicolored flowerheads that its taller cousin cannot produce. The French variety tends to be a bit more tame and comes in at a shorter stature.
I like to plant the French types with my vegetables because they don’t get as pushy as T. erecta, and offer a nice combination of color that matches my tomatoes and cucumbers. If purchased from a garden center they tend to be sold in eight-packs, my choice for best-bang-for-your-buck when buying live plants.
Durango offers intense colors with a warm orangish-red center outlined in a softer orange.

They’ll grow to be about a foot in height, so I don’t use them as often as other T. patula species, but their color really is something else.
Bonanza is a good choice to use for edging your vegetable garden or for other borders.
Bonanza Series Seeds, available from Trueleafmarket.com
Although it could potentially reach a height of six to twelve inches, it is best utilized for its spread of one to two feet. That’s a lotta flowers!
Disco is a “look at me, look at me!” kind of marigold, and I can dig that.

Reaching about a foot in height, this is a carefree flower that wants to be left alone so it can spread out and put on one hell of a show.
Petite would be my marigold of choice when used as a companion plant. It maintains good-sized flowerheads but rarely stretches to a height of more than six inches.

You get all of the benefits that you’re looking for with this type of flower, with little of the vigorous competitiveness found in some other varieties.
Signet (Tagetes tenuifolia)
T. tenuifolia is not commonly planted because it tends to grow obnoxiously. It will reach places you never intended and fight like a scrappy junkyard dog to hold onto its territory.
For that reason, I don’t use them often in my plantings. But if you’ve got the room for it, we have a reasonably tame variety to introduce to your home and garden:
The Gem series offers a relatively compact habit and is an edible flower, so that’s pretty cool.

A coworker plants the Gem series with nasturtium and sits back to enjoy the competition each plant offers.
Ready, Set, Grow!
They’re everywhere and are among the most recognizable flowers in the garden, but marigolds have to cheat to earn this reputation. They’re vigorous growers that require little care and are happy to deter pests and improve soil health, all while putting on a great show of color through the entire summer.
They’re also easily grown from seed! You can direct sow them into the ground, or start them indoors a few weeks before the end of winter. Planting these seeds is a great project for young and inexperienced gardeners, especially children, to get started on their green thumb early.
For the experienced gardener, a marigold offers an easy win and reliable performance that can be counted on year after year. Start seeds indoors about six to eight weeks before the last freeze and transplant those beauties right into the ground for fast satisfaction and a headstart on your neighbors.
I trust you’ve enjoyed this affectionate look at the delightful marigold. It’s been a treat writing this for our readers! Send us your comments below, and make sure to visit us regularly for the always-enjoyable experience of the Gardener’s Path.
