Snail Vine

Vigna caracalla, Phaseolus caracalla, Snail Flower, Snail Bean, Corkscrew Flower

Tender Perennial

 Customer Rating
This quick growing, evergreen twining climber is a close relative to the runner bean, grown for its pendants of twisted flowers, like coiled snail shells, up to 5cm (2Ó) across. The fascinating summer flowers are followed by cylindrical green fruits in late autumn. Requiring a minimum temperature of 15¡C (59¡F), Vigna caracalla is best grown in patio containers that can be moved indoors to a heated greenhouse or conservatory for the winter. Alternatively, grow snail vines outdoors as an annual. Height: 6m (20'). Spread: 2m (6').

patio, greenhouse, conservatory, exotic garden
Flowering Period:

Prior to sowing, Vigna seed should be chipped or soaked in tepid warm for 1-2 hours. Sow Snail Vine seed in pots or trays on the surface of a good seed sowing compost, and lightly cover with more compost or fine grade vermiculite until the seed is just covered. Place in a propagator or seal container inside a plastic bag at a temperature of 21-25C (70-77F) until germination which takes 14-30 days. Once germinated, grow snail vine plants on in cooler conditions.


When seedlings are large enough to handle, transplant into 7.5cm (3") pots and grow them on in warm, bright, frost free conditions. Pot on as required into progressively larger pots using a well drained compost such as John Innes No. 2. Provide the twining stems with an appropriate support, such as a climbing frame, trellis or horizontal wires attached to walls.

Feed and water Snail Vines regularly throughout the growing season and moderately in winter. Snail plants that are grown in large containers may be positioned outdoors on a sunny patio in summer, before returning them to a bright warm greenhouse or conservatory for the winter at a minimum temperature of 15¡C (59¡F). Prune lightly after flowering to contain the plant within its allocated space. Alternatively grow snail vine plants outdoors as an annual. When growing Vigna caracalla outdoors choose a sheltered sunny position in well drained soil, against a sheltered fence or wall.

  1. Hard to germinate

    By Susan Henry 14-06-2012

    Pack advice is to either soak or chip seeds, soaked and planted as instructed, six weeks later nothing had happened. Used a small knife to chip as per instructions and within 48 hours each seed had split, weather has been so poor for June that I brought them back inside, each plant now has second set of leaves so keeping fingers crossed.
