Like many of the annual vines, Cypress vine will sometimes reseed in the garden or the seeds can be kept each year for replanting. Its subtle beauty makes it more weird than wonderful. The flowers become small green balloon-like seed pods. Once the pods ripen the black seeds inside are marked with a distinct heart- shaped gray blotch, hence the name. Hyacinth bean, Dolichos lablab, has lovely purple flowers which are followed by glossy red violet pods.
Hyacinth bean is a purple lovers dream.
Even the leaves and stems are deep purple. It has been growing in gardens since the 1800's. It can grow to 15 feet and loves hot weather so wait until the soil has warmed before planting. Firecracker vine, Mina lobata, grows to 10 feet. The tubular flowers start out red but fade to orange then yellow.
