Botanical Name : Cardiospermum halicacabum
Balloon Vine, is a half hardy perennial, though gardeners often treat it as a half hardy annual which can grow up to 4m height. It is native to tropical areas in Asia, America, West Indies and Africa. Balloon vine is an attractive vine for fences or trellises with its dark green foliage and its pretty insignificant white flowers followed by large paper husk seed pods that look like balloons filled with air. Inside each pod are three pea-like seeds. As the seeds ripen, the soft green balloons turn brown and papery until they are light enough to fly away on the wind or float on water. The plant is also called "heartpea", "heartseed", "winter cherry" and "love in a puff," because the dark seeds carry a pretty, heart-shaped mark where they were attached to the pod.
