Catmint is any of various aromatic, ornamental, annual or perennial plants of the genus Nepet. It has opposite leaves and variously colored flowers with two-lipped corollas. Most cats find eating and rolling in catmint to be pleasurable and intoxicating. Cats are only attracted to it when it is in a withering state, or when the peculiar scent of the plant is excited by being bruised in gathering or transplanting.
The root is perennial and sends up square, erect, and branched stems, 2 to 3 feet high, which are very leafy and covered with a mealy down. Catmint is easily grown in any garden soil, and does not require moisture in the same way as the other Mints. It may be increased by dividing the plants in spring, or by sowing seeds at the same period. It should be planted in full sun, but can tolerate afternoon shade. It is very drought tolerant but does need a well-drained area.
