Snail vine is a cold-sensitive perennial member of the bean family, and it is one of the most intriguing plants we've ever grown! The uniquely shaped flowers of snail vine, or caracalla, actually resemble small snails!
This vining member of the bean family is one of the most intriguing plants we’ve ever grown! The uniquely shaped flowers actually resemble small snails! The fragrance of these distinct blooms is thought to be reminiscent of hyacinths, and Thomas Jefferson called this plant “the most beautiful bean in the world.” Perennial in its native region of Central and South America, snail vine is typically grown as an annual in areas that experience frost. We enjoyed an abundance of fragrant flowers all summer long, and are so excited to offer this incredible and wonderful vining plant! Rare and hard to find.

Growing Tips: Soak seeds in warm water overnight to aid germination. Sow indoors 6 to 8 weeks before last frost. Keep damp until germinated and increase humidity with a plastic dome. Sow seeds twice as deep as the seed is big. Set transplants out after frost. Plant in full sun/filtered shade. Snail vine thrives in late spring or cool-summer conditions. Deadhead regularly. Vines can reach over 10' long in a single summer, so be sure to grow up a trellis, arbor, arch, or fence.
