Gomphocarpus physocarpus, commonly known as balloon plant, balloon cotton-bush, bishop's balls, nailhead, 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 "balloonplant" is an allusion to the swelling bladder-like follicles which are full of seeds. Blooming in warm months. It grows on roadside banks, at elevations of 2800 to 5000 feet above sea level. The plant prefers moderate moisture, as well as sandy and well-drained soil and full sun.
Sowing advice: These seeds have already been thoroughly cleaned and cold-stored for several months. They should be sown into a well-drained, sandy compost at any time of the year, and covered thinly with sand or grit and kept moist. Keep at between 15 and 20 degrees C. Germination usually occurs within 4 to 6 weeks although some seeds may take much longer.
