Catnip 6 pack Seedling Tray

Catnip (Nepeta cataria) is a herbaceous perennial that thrives in much of North America and is very easy to grow. It has a clump-forming growth habit with square stems and triangular to oval, gray-green leaves with toothed edges that stretch around 3 inches long. Flower spikes appear in the late spring to early fall, bearing clusters of small blooms that are white with light purple markings.

The catnip plant is a fast and aggressive grower and can quickly spread throughout the landscape if not kept in check. It is considered invasive in a couple of spots in the United States, such as West Virginia and Maryland.1 It will reach its mature size in a single season and should be planted in the spring. Note that, while many cats enjoy catnip, the oils of the plant are technically toxic to them.
