Catnip—also called Catmint or True Catnip—is a perennial herb that is native to parts of Europe, Asia, and Africa. Plant catnip seeds inside or outdoors in full sun or partial shade. As the name implies, catnip is ideal for making cats happy and frisky, but it can also be used to flavor teas or to enjoy as an aesthetic element in the garden. Its purple blooms attract pollinators. Everyone loves it!
