Snail Vine Green An unusual rainbow bloom with fragrance. White, cream and green floral coils with a sweet perfume. The flowers are followed by bean shaped, green seed pods that age to brown. The flowers are pollinated by ants, and without ants you will not get seed pods. Snail Vines have large leaves, which are divided into three separate leaflets, each up to 13cm long. This creates a dense covering of foliage.
