Description

Gomphocarpus physocarpus, previously known as Asclepias physocarpus (it's name was changed in 2001), is an undershrub Milkweed perennial that can grow to over six feet! The plant blooms 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.

The flowers are small, with white hoods and about 1 cm across. The follicle is a pale green, and in shape an inflated spheroid. 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 brown seeds have silky tufts.

Seeds are rare and difficult to find.

Type: Hardy perennial

Height: Up to 6 feet!

Location: Sun or part sun

Hardiness zones: 8-10

Seeds per pack: 10

Note: Ornamental use only. These seeds and/or plants are poisonous.

Germination: Start these seeds right away for best germination rates. Start indoors. Your planting container should have holes in the bottom for excess water to drain. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Leave them at room temperature (20-22 °C, 68-72 °F) for 4 weeks. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination can be 30-90 days after the warming period, though some will take longer.
