Vigna caracalla is a leguminous vine from the family Fabaceae, originating in tropical South America and Central America. The species is named "caracalla", from the Latin for "hood or cloak", referring to the hooded shape of the open flowers. Some people suggest that this specific meaning comes from Caracas in Venezuela, but this is probably a misapprehension.
This perennial vine has fragrant flowers reminiscent of hyacinths. The buds, especially have a distinctive curled shape, giving rise to the common names "corkscrew vine", "snail vine", "snail creeper", or "snail bean". This vine is hardy in zones 9 and above, liking full sun and consistently damp soil. It prefers high heat and humidity and can become invasive if these conditions are met. In colder zones, it does well in a pot if it is overwintered inside.
