What is Calendula?

Pot marigold

The name “calendula” actually refers to a genus of roughly 15 to 20 species of perennial and annual plants in the Asteraceae family (often known as marigolds). Native to western Europe, southwestern Asia, Micronesia, and the Mediterranean, these flowers are referred to as pot marigolds, corn marigolds, desert marigolds, marsh marigolds, and more. 

The name “calendula” is a Latin diminutive of the word “calendar,” which means “little calendar,” with the name “marigold” referring to the Virgin Mary. More often than not, the specific type of calendula that you will grow in your garden is Calendula officinalis, or the pot marigold. 

Pot marigold is a medicinal flower that can be used to treat things like headaches, toothaches, and more. As a culinary herb, the calendula petals of this plant are edible and can be used fresh in salads or even dried to color cheese. It is often used as a substitute for saffron and can add vibrant color to everything from poultry dishes to soups and stews. 

Not only that but Pot marigold is a powerful anti-inflammatory and wound treatment. It is often used to repel pests from the garden since its strong aroma tends to drive pests away from more desirable plants. 

Growing Calendula Flower

Calendula flower is easy to grow and can be grown in most sunny locations and most types of soils. Although it is technically a perennial, it is grown as a manual in colder regions where winter survival is challenging and in hot climates where summertime is more of a challenge.

Many gardeners consider calendula to be the easiest and most versatile flowers they can grow. Because this plant can tolerate most types of soil as well as dry spells, it is a popular choice for seasonal color. 

A longtime staple in British cottage gardens, calendula is easy to grow in the herb or flower garden. It is moderately frost tolerant and can add long-lasting beauty to either environment. It will readily reseed. Grown as an annual in most places, it is perennial in zones 9 to 11. 

Plant your calendula flower in poor to average soil. It does not need to be overly fertile and in fact, soil that is too fertile can cause your plants to grow slowly or in a stunted fashion. Instead, grow in poor soil and water only occasionally – and make sure the organic potting soil is well-draining, too! 

Calendula prefers somewhat cooler temperatures so filtered sunlight or a bit of shade is ideal. Full sun is best in cooler areas although a bit of afternoon shade is always appreciated.

How to Plant Calendula

Calendula is easy to grow either from seeds or transplants. 

If planting calendula seedlings, wait until the danger of frost has passed before you transplant. If you’re growing from seed, you can sow them just before the last expected first date in your area. 

You can also start your seeds indoors about six to eight weeks before the last frost date. Sow the calendula seeds thinly in a moist seed starter mix. You can use plant seeds that you collect from the calendula blooms and save them from season to season. 

Again, calendula reseeds readily. Most plants will bloom within two months of seeding.

Caring for Calendula

Here are some tips to help you care for your pot marigold plants once seedlings are transplanted (or appear after sowing seeds). 

Watering 

Calendula likes to be a bit on the dryer side and will actually suffer from rotted roots in dense, wet soils. Therefore, it’s important that you only plant in well-draining soils (or in containers). 

Water regularly until the plants are established. When your plants are mature, only occasional bouts of watering are necessary (and most of your plants’ watering needs will be supplied by regular rainfall). 

Fertilizing

Calendula plant doesn’t need much in the way of feeding. In fact, infertile garden soil, calendula requires no supplemental feeding – fertilizing too much can actually lead to stunted growth or can cause your plans to become leggy and spindly. 

The only calendula plants that require regular fertilizing, in fact, are those grown in containers or very marginal soils. Use a balanced water-soluble fertilizer calendula about once per month, since containers leach nutrients more quickly than regular garden soil.

Pests and Diseases 

Calendula is prized for its hardy nature. Although no plant is truly resistant to all pests and diseases, calendula is one of the few that is largely free of problems. It can sometimes fall victim to powdery mildew, but you can keep this disease at bay by ensuring good air circulation and space between plants.

Keep the area around your plants free from debris and weeds, which will reduce the likelihood of snail and slug damage. Other pests to watch out for include whiteflies and aphids. You can spray with water to blast these pests off your plants or treat them with insecticidal soaps. 

Otherwise, you shouldn’t have to worry about too many diseases and pests affecting your plants!

Harvesting Calendula

If you choose to harvest your calendula flowers, whether for ornamentation in a vase or for culinary or medicinal use, do so late in the morning. Wait until the dew has dried but not so long that the sun has become hot and desiccating. 

You can pick flowers when they are fully open. To dry them, spread the cut heads on a screen in a shady, dry environment. Turn the calendula blossoms until they are dry, papery, and brittle, then store them in glass jars until you are ready to use them. 

Deadheading and Pruning Calendula Flowers

When deadheaded regularly, calendula can bloom continuously from spring until fall – and beyond! In warmer environments, however, your calendula may briefly pause its blooming in order to gain a respite from the summer heat. However, as soon as the temperatures cool in the fall, the blooming will return. 

You don’t need to prune your calendula plants, but regular pinching can prevent stalks from becoming too tall and spindly. 

If you’re looking for a beautiful flower that is easy to grow and care for, calendula might be your best bet. With its large range of colors, it can add brightness to any vegetable garden or porch planter in need of a pop of color. 

From planting tips to how often the flowers should be watered, we have covered all the basics here for you.
