Catnip is a hardy herbaceous plant with a bushy, upright growth and multi-branched stems.

Catnip has a strong, minty scent with a hint of citrus, which is particularly pronounced when the leaves are crushed. The flavor is minty with a slightly bitter undertone.

Catnip is known for its effect on domestic cats. When cats smell the nepetalactone in catnip, it can induce behaviors such as rolling, rubbing, purring, and playfulness.
