CATNIP

Catnip has all the characteristic earmarks of a member of the mint family: stems square in cross-section, leaves opposite and fragrant, and small flowers in tight clusters at the ends of branches. This perennial herb may grow up to 3 feet tall and be highly branched. The gray-green to green leaves are heart-shaped with scalloped edges and are often crowded toward the top of the plant. The flowers are white, dotted with purple, two-lipped, and produce four tiny, dark nutlets per flower.
