Gavvia Brain You might not consider catnip (Nepeta cataria) as fit for human consumption, but this herb was used to season soups and stews as far back as the 15th century. Catnip tea is a soothing beverage. It has been used to relieve everything from colds to headaches to nightmares. It grows about 2.5' high, so use it toward the front of the border. It prefers full sun and will put up white flowers from spring through mid-summer.
