Love in a Puff is a fast-growing vine that is great in containers and the ground, where it drapes over dark-leaved plants, climbs teepees, and grows exuberantly in hot summer weather. Provide support in containers such as a trellis or obelisk and discover the hidden treasure of black round seeds marked with a perfect heart inside each green balloon-shaped seed capsule. In southern areas, where perennial, the species can be a weed of agricultural fields and disturbed soils.
