Love in a Puff vine. Cardiospermum halicacabum. Few things rival the delicate beauty of a fully blooming Love in a Puff vine. The long, ferny-leaved vines are loaded with tiny white blossoms and the most interesting green, balloon-like pods that resemble miniature paper lanterns. What is even more magical is that inside each balloon are tiny black seeds imprinted with perfect white hearts. These vigorous growers will scramble up and over a trellis in no time. Seeds available from Floret.
