Enjoy a cup of hot catnip tea while watching your cats frolic in a patch of this fragrant, attractive plant. Catnip is a multi purpose plant. The tea is very pleasant and has a lemon-mint flavor and fragrance. Along with fresh catnip planted in pots indoors, fresh catnip toys will provide your cats with hours of fun. But be warned; you may no longer be their best friend! Catnip is very hardy and grows in almost any soil.
