Catnip is a tall herb, resembling mint, with grayish-green leaves and white flowers. Catnip can grow to be 50-100 centimeters tall which makes it the perfect feline companion.

Catnip is one of the plants in the genus Nepeta that naturally produces nepetalactones. The colorless oils of the plant also act as an insect repellant.

Catnip is hardy in zones 3-9 and prefers a sunny location. Catmint will grow in zones 4-8.
