Balloon Vine is an annual tropical climber vine with ribbed stems. The plant is also known as Cardiospermum halicacabum, Heartseed, or Love In A Puff. The plant is native to Africa, the Caribbean, and tropical South America. The vine has long, fern-like leaved vines that are loaded with small white flowers and fascinating green, balloon-like pods that look like miniature paper lanterns. The flowers have four petals, are white, fragrant, and grow in clusters. The plant is sensitive to cold, so wait until the weather has warmer to plant it outside. The plant flowers from late summer to fall. The balloon-like pod is a fruit that is green, drying to brown. Allow the pods to dry on the plant; break them open to collect the seeds. Inside each pod, are tiny black seeds imprinted with perfect white hearts. The plant is an enthusiastic grower and will clamber up a fence or trellis in no time. It will grow 6-10 feet. Balloon Vine can be used in floral arrangements. Plant it in full sun. The plant also has medicinal properties. The plant is hardy for zones 8-11.
