No other flower in the cutting garden glows with cheerfulness quite like calendula, commonly called the pot marigold. This bright yellow and orange flower is not only calming to my spirit, but also has many other benefits: it attracts pollinators, repels pests, has healing properties, and is edible! Learn more about growing calendula. 

Benefits of Calendula 

Included in a mixed bouquet, calendula (Calendula officinalis) flowers are sure to gladden the hearty of the recipient.  Irresistible waves of bright yellow and orange daisy-like flowers greet me on my morning rounds, lifting my mood even on the worst of days.

  • Calendula blossoms can be used in cooking—eaten fresh in salads, added to rice, or dried and used as a poor man’s saffron, calendula petals make an ordinary meal seem special. See our recipe for Mixed Greens With Calendula.

  • Calendula has been used medicinally for centuries. Ancient Romans grew them to treat scorpion bites! In the Middle Ages calendula was a common remedy for everything from smallpox to indigestion. Today’s herbalists use it to make a healing salve for sunburn, chapped lips, minor burns, cuts, and scrapes. See more about calendula’s healing properties.
  • Calendula is a wonderful companion plant in the garden.  Bees and native pollinators are drawn to these flowers, making them a useful addition to your vegetable garden. Plus, calendula repels many pests!

Types of Calendula

The calendula family includes about 20 species of bushy annuals and a few perennials that are native from the Canary Islands through the Mediterranean area to Iran. They were found growing wild in the Holy Land by crusaders who brought them back to Europe. Legend has it that St. Hildegard of Bingen gave the plant the name “Mary’s gold” in honor of the Virgin Mary. To this day calendulas are sometimes called “pot marigolds” though they are unrelated to regular garden marigolds (Tagetes).

Calendula Varieties

  • ‘Pacific Beauty’ is my favorite but at one time we grew 8 different kinds. There are lots of interesting varieties.
  • For something unusual try ‘Porcupine’ which has spiky, bright orange, quilled petals,
  • ‘Touch of Red’ has dark red underneath and on the edges of each petal.
  • ‘Triangle Flashback’ has a soft, apricot-pink color.

How to Grow Calendula

Calendula is easy to grow from seeds directly sown in the garden.

  • The more sun, the better. 
  • Soil needs to be moderate-rich and drain well. Calendula will tolerate poor conditions but perform better when it has nourishing soil. Once established, calendula do not need any extra fertilizing or feeding.
  • Plant seeds early spring onward or start them indoors and set out the sturdy seedlings. They can be started indoors 6 weeks before the last frost date for extra early blooms.Peas, Carrot,
  • Calendula grow nicely in the vegetable garden. Good companions are: Cucumbers, Tomatoes, Asparagus, Spring salad vegetables.
  • The flowers bloom best in cooler weather with low humidity.
  • Cut them back and they will reward you with new growth and more flowers when the weather cools off. These plants are pretty tough and can take some frost. They will keep right on blooming until a harden freeze finally kills them.
  • Allow some plants to produce mature seeds to scatter where you want to see calendula seedlings in subsequent seasons.

Calendula Salve

If you would like to try making a simple calendula salve, here’s an easy recipe:

  • Steep one cup of fresh calendula petals in one cup of olive oil in a glass jar on a sunny windowsill for about a week.
  • Strain the oil.
  • Melt ¼ cup of beeswax and mix in the oil.
  • Pour into small sterilized jars and seal.
  • Let solidify overnight before using.
  • For the fullest effect, harvest the petals during the hottest part of the day, when the resins have risen to the surface of the flower.

A word of caution: People with allergies should test the salve on a small spot on the inside of the forearm and monitor it carefully for any adverse reactions.

This is one plant that is good for the garden and for the gardener alike. Make room for some comforting calendula.

Even the tiny tree frogs love it!

Love this Herb!

I make a facial toner and a face cream with Calendula as the base, its very popular for evening skin tone. Its also very good for men with "shaving rash". The Calendula is the Go to Herb for me!

Awesome Calendula

I have been growing these happy little faces for many years. Surprising how few folks have not hear of them. I mix them w/ blue Bachelor Buttons.

Calendula Salve

I planted calendula this year for the first time and it is doing wonderfully. I want to make the salve with it and was wondering if it would be best to dry the flowers first before infusing them in oil since I had read to dry dandelion flowers a bit first so the moisture from the flowers wouldn't create mold in the oil. Has this ever happened to you with using fresh calendula flowers?

I have never had any mold

I have never had any mold form. I pick the flowers during the hottest part of the day so any dew has dried and  the resin comes out on the petals. They are actually sticky. I have never tried drying them first but it may work if the resin dries on the petals and then becomes infused into the oil. Give it a try!

Mold/preparation

I make my oil with fresh but I use a yogurt maker to keep the temp of the oil at (or around 110 degrees). You can use dried but I took a recipe from "James Green Herbal Medicine Makers Handbook" (Ethyl Oil preparation). "Sticky" herbs of any kind - Grind your dried herb, LIGHTLY dampen with alcohol until 'just' damp, let it sit for an hour, then add to oil. The alcohol softens and breaks down the sticky substance and will not effect the quality of the oil. Works like a charm. By the way, I collect more of the petals than buds, this gives the oil a beautiful glowing orange color.
