Cardiospermum halicacabum has several common names, such as Love-in-a-puff, Balloon vine and Heart seed. A gentle vine, it can still grow anywhere from 7 to 10 feet tall. The leaf shape is unusual, the flowers are tiny, and the seed pods look like small green lanterns. But the seeds themselves are what is really interesting. They are small, round balls that have a perfect white heart on them.-Love-in-a-Puff. Pkt. 15
