Snail Vine Seeds

(Cochliasanthus caracalla) Snail vine, or caracella, is a cold-sensitive perennial member of the bean family, and it is one of the most intriguing plants we've ever grown. The flowers actually look like little snails! Perennial in hot climates, snail vine is typically grown as an annual in areas that experience frost and only hardy in USDA zones 9-10.
