Gomphocarpus fruticosus

Common Name:
Swan Bush

Description:
Gomphocarpus, commonly known as Swan Bush or Balloon Cotton Bush, is a fast-growing perennial shrub admired for its unusual balloon-like seed pods and strong ability to attract butterflies, particularly Monarch butterflies. The narrow grey-green foliage provides a soft, airy texture, while clusters of small creamy-white flowers appear through the warmer months before developing into the distinctive inflated seed pods that add ornamental interest. Thriving in Melbourne’s climate, Gomphocarpus performs best in a sunny position with well-drained soil and tolerates dry conditions once established. Its informal growth habit makes it ideal for cottage gardens, wildlife gardens and naturalistic plantings. This hardy and low-maintenance plant brings movement, texture and ecological value to the garden while serving as an important host plant for butterfly larvae.
