Balloon Plant

Balloon Plant (Asclepias physocarpa)

Balloon Plant (Asclepias physocarpa), also known as Swan Plant or Hairy Balls Milkweed, is a unique, fast-growing perennial prized for its unusual balloon-like seed pods and pollinator-friendly flowers. This striking species produces clusters of small, pale greenish-white flowers that attract butterflies, bees, and other beneficial insects. As the flowers fade, large, spiky, lime-green seed pods develop, creating a dramatic focal point in the garden. Native to Africa, it thrives in warm climates and is an essential host plant for monarch caterpillars.
