Botanical Name

CALENDULA officinalis

Plant Common Name

Pot Marigold

General Description

Cheerfully bright when in flower, pot marigold is a bushy annual that originates from Europe and the Mediterranean region. It is very easy-to-grow but it best in climates where summers are temperate and cool, though plants can be surprisingly drought tolerant once established. Often it is only grown as a cool season bedding plant.

During the growing season, it bears single, double or semi-double daisies that come in shades of cream, bronze, yellow and orange. These appear amid many soft medium green leaves and are highly attractive to bees and butterflies. The petals of pot marigold flowers are edible and add a spicy flavor to salads.

This annual is long-blooming and highly rewarding. It prefers full sun to partial shade and moist, well-drained, fertile soil. Regular deadheading will encourage continuous flowering as will regular food and water. Enjoy pot marigolds in mixed borders, containers, herb gardens or vegetable gardens. It can be grown in subtropical regions in the cool dry season when days are warm and sunny but nights cool and comfortable.
