Balloon Vine

Cardiospermum grandiflorum

Balloon Vine is a vigorous climbing vine recognised by its distinctive inflated balloon-like seed capsules. It smothers vegetation and can form dense blankets over trees and shrubs. The vine has spread rapidly in Queensland, particularly along the coast.

How to Identify

  • Climbing or scrambling vine to 10+ metres
  • Compound leaves with 3 groups of 3 leaflets
  • Small white flowers
  • Distinctive inflated capsules (balloons) 3-5cm
  • Black seeds with heart-shaped white mark
  • Tendrils for climbing

Where It Grows

Riparian areas, disturbed sites, forest edges, fence lines. Prefers moist conditions but tolerates dry periods.

Environmental Impact

  • Smothers trees and shrubs
  • Can form impenetrable curtains of vegetation
  • Seeds spread by water and wind
  • Difficult to remove from tree canopies
  • Reduces habitat quality

Control Methods

  • Hand pull small plants and seedlings
  • Cut and paint larger vines
  • Foliar spray for ground infestations
  • Collect and destroy seed pods before dispersal
  • Follow up for seedling regrowth
  • May need tree climbing for canopy removal

Seasonal Activity

Flowers spring to autumn. Seeds disperse in dry pods.
