Visitors looking over my garden in the fall, always ask what the strange-looking plant is that is forming large spiny pods. Growing in my veggie garden, because of the amount of space the plants take, my Gymnocarpus physocarpa, or “Hairy Balls” are a conversation starter. A Milkweed family member, another common name is Balloon Plant. Native to South Africa, this plant is invasive in tropical climates, but in my zone 6-7 area, winter cold keeps it in check.
