Vigna caracalla

Snail Vine
Fabaceae (Leguminosae)
Annuals, Ground covers, Perennials, Vines

Perennial vine sometimes grown as an annual. Tropical American native that generally resembles pole bean in form and foliage. The flowers are different, though: fragrant, cream to pale purple spring and summer blossoms have lilac or purple markings, twisted keel petals that are coiled like a snail shell—odd and pretty. Twines rapidly to 10–20 ft.; good summer screen or bank cover. Evergreen in frostless areas; in colder regions, cut plant to the ground if frost kills top. Sometimes sold as Phaseolus gigantea.
