Scientific name: Calendula officinalis

Calendula, also known as pot marigold, has been used for generations, and  grows edible, nutritious flowers which can be used in soups and salads. It’s a hardy plant that has an extended blooming season, and in some warmer climates can grow year round. This herb is very effective for cleansing the lymphatic system and belongs to a family of cancer-fighting plants. Fun fact: if the flower heads are closed after 7:00 AM, it will rain that day.

Pick and use the flowers when they are sticky. The stickiness is a resin that has anti-fungal properties.

How to Grow


Where do you live?

This tough plant can grow just about anywhere when the ground is thawed.

Put ’em in the ground

Some seeds will replant themselves for the next season, otherwise collect seeds in the fall and plant in the spring.

  • Full sun
  • Good fertile soil (ideally)
  • Occasional watering

Throughout the summer and into the fall if there are no signs of mildew. Pick flowers when it’s sunny out, as they will have their best healing benefits.


Calendula is actually one of a group of plants used as “companion” plants. The scent helps deter harmful bugs away from other plants you might be growing, so it will do the work for you!

They help deter bugs like:

  • Mexican bean beetles
  • Aphids
  • Cabbage maggots
  • Asparagus beetles
  • Tomato hornworms
