Cardiospermum grandiflorum
family: SAPINDACEAE
Description
  • Vigorous highly invasive climber from tropical Africa, Asia and America; climbs by means of tendrils to the top of the canopy, blanketing vegetation at all levels.
  • Light green leaves are compound with three sets of three leaflets which are thin, toothed, and softly hairy.
  • Small white flowers are produced from summer to winter.
  • The fruit is a light green thin-walled, papery, inflated capsule resembling a ribbed balloon, containing three black seeds.
Dispersal
Often dumped on bushland edges. The capsules can be carried by wind and float freely on water, dispersing the plant along waterways. Also regrows from root fragments.
Impact on Bushland
Favours creeklines and the margins of rainforest, grows rapidly into the tops of trees, forms a thick curtain of stems, excludes light, harbours pests and diseases. Weight contributes to canopy collapse and ecosystem destruction.
Distribution
Lower Blue Mountains.
Alternative Planting
Old Man's Beard (Clematis aristata); Wonga Vines (Pandorea species); Wombat Berry (Eustrephus latifolius); Water Vine (Cissus antarctica). Clematis (Clematis montana).
Control
Dig out or treat as for Vines and Scramblers. Bag Capsules. Follow up with seedling removal.
