How to Grow Pot Marigold: A Medieval Herb for Modern Times


Pot marigold, or Calendula officinalis, has its origins in medieval Europe, where it was blended into soothing salves and stirred into restorative elixirs.

Harvest whole pot marigold heads for use in herbal preparations that soothe and heal:

Estimates place its introduction to the United States at the time of the European settlers’ arrival in the 1600s.

Also called English marigold, C. officinalis looks like the true marigold flowers of the Tagetes genus that includes the French marigold, T. patula, and the African marigold, T. erecta.

Calendula and Tagetes varieties are members of the Asteraceae family of plants that includes daisies, chrysanthemums, and sunflowers.

A Three-Season Bloomer

If you’re looking for a flower that makes a colorful splash in the garden from spring through summer and well into fall, this is the plant for you!

To grow pot marigold, begin with viable seed. For this plant, that means it should be no more than a year old to ensure germination.

I like to start annuals indoors , so my C. officinalis cultivation is usually underway by late March. Then, when all danger of frost has passed, I transplant the sturdiest seedlings outdoors, and keep them moist and weed-free until well established.

As the plants enlarge, I pinch back leggy stems to encourage bushy growth, and deadhead spent blossoms to ensure a continuous display of color throughout the growing season.

Pot marigold is an annual that self-sows, so if you don’t deadhead and your climate is accommodating, you may find that it behaves like a perennial. If you want to give it a try, remove spent blossoms sporadically, or not at all, to allow seed to form and scatter.

You may grow this plant successfully in almost every zone, in dwarf and full-size varieties, for a profusion of yellow and/or orange flowers that are not only pretty to look at, but edible, too.

Harvest whole flowerheads on a sunny afternoon for use in herbal preparations that soothe and heal, recipes that call for golden color, or a tangy garnish.

Individual petals may be separated, dried, and stored in an airtight container in a dry location. Before use, inspect petals closely for mold, which may develop as the result of moisture buildup, and discard if necessary.
