Corkscrew Vine (Vigna caracalla): Spiraling Blooms of the Tropics

Corkscrew vine (Vigna caracalla, syn. Phaseolus caracalla) is a stunning tropical climber named for its unique, spiraled flowers that resemble curled snail shells. The fragrant blossoms emerge in shades of pale purple, cream, and pink, dangling in graceful racemes from vigorous twining stems.

Growth and Bloom

This perennial vine can climb 20–30 feet in a single season, making it ideal for pergolas, arbors, or sturdy trellises. The flowers appear in late summer to fall and are highly fragrant, especially in the evening. The foliage consists of trifoliate leaves that provide dense coverage.

Care

Provide full sun, rich soil, and consistent moisture. In zones 9–11, it is evergreen; elsewhere, grow as an annual or overwinter indoors. Feed with a balanced fertilizer during active growth. The vine may need strong support due to its rapid, heavy growth.
