Calendula, also known as pot Marigold, is a stunning Mediterranean plant with a daisy-like appearance that is part of the Asteraceae family. It is often grown as an annual flower in cooler climate zones, but in warmer climates, it is a short-lived perennial.
Today, gardeners enjoy these plants for their vibrant, cheerful flowers that bloom quickly after planting in the spring. With a range of colors from subtle shades of pink and cream to bright yellow, orange, and red, calendula is a popular choice for garden beds and containers.
Most common Marigold varieties:
- Bolero (French marigold)
- Colossus Red Gold
- Court Jester
- Golden Guardian
Calendula is easy to take care of, and can also tolerate poor conditions. You need to keep in mind that it needs full sun but may wilt in extreme heat. A quick tip: pinching back young plants promotes compact, bushy growth, and deadheading old flowers encourages reblooming.
- Soil: Calendula plants prefer well-drained soil high in organic material and can tolerate a wide range of soil pH but prefer slightly acidic to neutral soil.
- Water: It is very important to avoid overwatering these plants. Water them frequently until they are established, after which mature plants only need occasional watering.
- Light: Calendula plants usually prefer full sun but may require some afternoon shade during the hottest months to avoid wilting.
- Temperature: it likes mild summer temperatures but can die in very hot climates, while a hard freeze can also kill the plant. Just protect the plant from frost with a blanket or three to four inches of mulch.

Propagating calendula plants is pretty straightforward so beginner gardeners are in luck here. Just start by germinating seeds indoors in a seed starter mix about 6 to 8 weeks before the last frost or sow them directly into the garden just before the last spring frost. These plants will also readily self-seed in the garden, but don’t mistake the seedlings for weeds.
You can also propagate them by taking cuttings (like propagating Elephant Ears), but using seeds is the most common method.
