Perennial & Biennial Seeds

Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

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

 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 (2") 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').
