Gomphocarpus physocarpus E.Mey. |
Asclepias physocarpa (also known as Gomphocarpus physocarpus, commonly balloonplant, balloon cotton-bush or swan plant) is a species of milkweed. The plant is native to southeast Africa, but it has been widely naturalized. It is often used as an ornamental plant. The name "Balloon plant" is an allusion to the swelling bladder-like fruit.
Asclepias physocarpa is an undershrub perennial herb, that can grow to over six feet. The plant blooms in warm months. It grows on roadside banks, 2800 to 5000 feet. The plant prefers moderate moisture, as well as sandy and well-drained soil and full sun.
The flowers are small, with white hoods and about 1 cm across. The capsule is a pale green, and in shape an inflated sphere. It is covered with rough hairs. It reaches three inches in diameter. The leaves are light green, linear to lanceolate and 3 to 4 inches long, 1.2 cm broad. The seeds have silky tufts.[1][2]
The plant is a food source for the caterpillars of Danaus butterflies. It is also popular in traditional medicine to cure various ailments.[3]
