Also known as Gomphocarpus, Hairy Balls, Swan Milkweed, and Balloon Plant, this unusual ornamental is grown for its large, papery, balloon-like seed pods that can be used fresh or dried in arrangements. The plants are tall and willowy with thin, oleander-like leaves and small clusters of delicate white flowers with pale-purple centers. While the flowers are pollinated primarily by wasps, the foliage is a good food source for monarch caterpillars. Its prodigious spheres are real conversation starters!
Gomphocarpus is a perennial in zones 8-11 but is grown as an annual elsewhere. Use caution when harvesting: this plant's milky sap can be irritating to the skin of some sensitive individuals.
