Gomphocarpus physocarpus, has many funny names.  Hairy Balls, Balloon, and Family Jewels to name a few.  An African native -annual in cold regions. Often confused with Swan Milkweed, (Gomphocarpus fruticosus available in my eBay store).   Easy enough to do because the seeds, plants and blooms are indistinguishable from each other.  The only difference is the shape of the pods.  Delicate creamy white flowers weep from stalks that quickly grow 6-8 feet long, branching slightly. Long narrow leaves. Pods are green and knobby with soft spikes that look like hairs. Good container plant. Pinching back while young makes a bushier plant. These are a huge Monarch attractants for egg laying.  The tender leaves are perfect for the smaller caterpillars.

Instructions: Slow germinator: 10 - 28 days. Warm water soak for 1 wk.  Pour out onto soil. Keep moist & warm until fully germinated. Prefers full sun. A seed heating mat is recommended if starting indoors. Do NOT cold stratify.
