Part of the mint family, Catnip is a beloved treat for your favorite kitty. It's easy to grow, does well in containers, and can be used either fresh or dried as a feline treat. Leaves can also be used to make tea for yourself. In summertime, the plant will produce lovely white flowers decorated with purple dots. If you grow it in the garden, you may need to plant a number of stakes throughout the area to keep cats from rolling in it.
