Catnip (Nepeta cataria)

flowering catnip

Description

Catnip is a hardy perennial plant that grows to a height of 3 to 4 feet. The heart-shaped leaves are green about and gray below. The plant has purple flowers that draw pollinators.

Culture

Catnip is a hardy plant that will grow in sun or shade. It can be grown from seed or propagated by division. When young, the plants are decorative but as they grow older, they become scraggly. It’s best to plant catnip as a background plant. Leave 24" between rows and 18" between plants. 

Harvesting

Cut and dry the mature leafy tops and leaves.

Use

Catnip leaves are used for tea and seasoning and also are attractive to cats.
