Phaseolus giganteus

Purple Snail Vine is an amazing heat tolerant vine that continuously blooms with large purple pea/bean like flowers with shades of white, lavender and pink. It?s crazy how much confusion exists between this and Corkscrew Vine. Sometimes, you get seeds of this species when ordering Corkscrew Vine seeds. We still use Phaseolus giganteus as the botanical name but many claim this is not a legitimate name. It is most likely Sigmoidotropis speciosa. Purple Snail Vine doesn?t have the large clusters of flowers like Corkscrew Vine, nor is it as heavily scented. Its blooms are pleasantly scented though with a slight hyacinth-like fragrance. Both species are native from Mexico to S. America and were both brought to Portugal from Brazil in the 17th century.
