When planning what annuals I want in my garden, calendula is a no-brainer addition. It’s a staple in my herbal apothecary, being a powerful wound healer and an amazing skincare herb. And did I mention the sunny yellow flowers are also a stunning ornamental? Here’s everything you need to know about planting calendula and harvesting it for recipes.

There are a lot of great reasons to grow calendula. In addition to their bright orange and yellow daisy-like blooms which bring cheer to the garden, planting calendula attracts good insects like bees and butterflies while deterring unwanted pests.

But most importantly, calendula has a long-standing reputation as a natural anti-inflammatory skin care treatment. It’s easy to grow, harvest, and dry in the home garden and beneficial for use in recipes and DIY beauty products, a practice that dates back to ancient history.

Calendula comes in many kinds of warm, sunshine hues.

Calendula (Calendula officinalis) is part of the daisy family, Asteraceae, and also goes by the name pot marigolds. While often called marigolds, they are not the same species of marigolds that you often find at the garden centre, Tagetes.

The calendula flowers open in the day, and close at night as the sun sets. Culpeper called the flower, “An herb of the sun.” And the bright yellow and orange hues sure feel like a bucket of sunshine in the garden.

The flowers bloom from spring to fall as long as you continuously deadhead them. The stalk will support many branches and flowers with oblong leaves. The plant has a signature sticky feeling, thanks to the resin and other constituents in it.

When harvesting or working with calendula, your hands may feel tacky from the resin.

Calendula Benefits

Calendula is often harvested to use in tea, tinctures, and oil and vinegar infusions. The early Greeks and Romans used to drink calendula tea for upset stomachs as well as adding the flower to soups and stews to improve digestion. The bright hues were often used to dye fabrics and cosmetics.

Most commonly, and historically, Calendula is used in salves, ointments, or as a poultice for treating wounds. It has antibiotic, anti-inflammatory, hemostatic, and tissue healing properties to use for scrapes, cuts, burns, rashes, bruises, bites, itchiness, sunburns, and fungal skin infections. The salicylic acid in the calendula also helps relieve the pain.

When taken internally, it’s great for the digestive system and is known to support the gallbladder and the liver. Thanks to its antibacterial and antiviral properties, it can also work as an immune stimulant. When hot, it works as a diaphoretic by stimulating circulation and sweating.

Calendula can easily be started from seed, either indoors or out. To sow the seeds outdoors, the best time to plant them depends on what type of climate you live in, but a good rule of thumb is to plant them just after the last frost of the season.

When planting calendula indoors, plant them approximately 8 weeks before you plan to move them outside into the garden and allow them to germinate in the dark for a week or two.

Plant the seeds about ¼” deep. Dwarf calendula should be spaced 8” apart, while the taller varieties should be about 20” apart.

When growing calendula, the plant likes lots of sunlight and can become leggy if they do not get enough, so plant them somewhere bright but not extremely hot.

Calendula is so easy to grow from seed that I wouldn’t ever buy starts.

During the hottest time of the year, water calendula once a week to keep them perky and encourage blooming. Otherwise, calendula can survive in dry conditions.

Deadhead old flowers regularly to promote new growth, and if the plant begins to look wilted or otherwise unhealthy, cut it back quite drastically. It will come back healthier and bloom later in the year.

Calendula can fall victim to powdery mildew, a fungal disease that can be identified by white patches on foliage. Remove the affected area of the plant as soon as you notice it and dispose of it to prevent the disease from spreading.

Many gardeners grow calendula in the vegetable garden to attract pollinators and repel pests. Calendula contains the phototoxin alpha-terthienyl, which protects against root-eating nematodes. Nematode-susceptible tomatoes do very well with companion-planted calendula.

To deter cabbage worms, you can also plant calendula near cruciferous vegetables such as cabbage, cauliflower, broccoli, and Brussels sprouts. These fragrant flowers are also reported to mask the scent of the vegetables, protecting them from veggie-sniffing insects far and wide.

Calendula, alongside borage and marigolds, are great companion plants.

Organically-grown calendula flowers are the gold standard for medicinal plants, so you will probably want to preserve some for home use.

You can get lots of blooms to harvest spring through fall, as long as you make sure to keep snipping the flowers to harvest. The fresh or dried florets are typically used for medicinal reasons, but it’s time-consuming to pick them all, so most people pick the petals.

Harvest flowers when fully open and spread them out on a screen or in a shallow basket to dry. They are ready when the petals feel papery to the touch. Store them in an airtight jar and use them in natural beauty recipes or tea.

I also like to let some calendula flowers go to seed, where they form thick, crescent-shaped seeds. They’re easy to collect and save for next year’s crop.

Calendula Uses

I’m a super fan of calendula, so I have lots of beauty and medicinal recipes that I use calendula in. For many of my recipes, I infuse dried calendula into oil. I have step-by-step instructions for infusing calendula flowers, either using the cold or hot infusion method.

Calendula is also an edible flower, so you can also use the flowers fresh as cake decorations or add the petals to a fresh salad.

Here are some of the recipes on Garden Therapy that include calendula flowers:

Use calendula salve to harness the wound and tissue healing properties of calendula.
Is calendula a perennial?

Calendula is an annual. The best way to ensure that you have calendula for next year is to let some of your calendula flower heads go to seed at the end of the season. These will turn into crescent-shaped seeds you can store and plant in the spring.

Is calendula edible?

Yes! Calendula has a slightly bitter taste that can lean toward spicy or tangy. It’s highly pigmented, so it can also give food a yellow tint.

Is calendula safe for dogs?

Generally, calendula is safe for dogs and other animals. Like most plants, if a dog eats lots of the plant, it may get an upset stomach. Calendula is also used to promote contractions during pregnancy, which can happen for humans and animals if ingested.

What’s the best way to dry calendula?

Pop off the heads of the calendula and discard the stems. Lay out the calendula on a tray, drying rack, or dish and wait for them to dry. Place them outside of direct sunlight and humid conditions. You can store the petals in an airtight container when they feel papery.
