Calendula Officinalis, commonly known as the pot marigold, is an easy to grow annual flower. The varieties of calendula blossoms come in different shades of yellow, orange, pink or cream.

The leaves are long, slim and medium green. Though it is referred to as the “pot marigold” the flower is not actually in the marigold family. In reality, calendula is related to chrysanthemums and daisies.

Pot marigolds are used often as a medicinal herb but they are also easy to grow and make a colorful addition to the home garden.

If you have super hot Summers, you can grow your plants in containers so that you can move them to a shaded area during the hottest part of Summer.

Add mulch around the base of the plant to help control weeds. Pot marigold is a prolific bloomer but make sure to deadhead it so new flowers keep emerging. The blossoms will turn to face the sun as it moves around through the day.

Insects like aphids are particularly attracted to pot marigolds. Look for small white specks on the underside of the leaves.

Spray these bugs with a soap and water solution to remove them. The plant can also develop mildew problems if grown in humid areas. Apply a fungicide to help with this.
