Dutchman's pipe (Aristolochia spp.) is an environmental weed that is widely promoted as an unusual, easily cultivated ornamental plant. It is very similar to the native plants which are a natural food plant for a number of Australian butterflies, but is however a deadly alternative as it tricks the butterflies into laying their eggs on its leaves and then poisons the larvae when they hatch and begin to feed. The survival of the rare Richmond birdwing butterfly Ornithoptera richmondia is threatened by this plant.
Dutchman's pipe is a declared Class 3 pest plant under Queensland legislation.

The best form of weed control is prevention. Treat weed infestations when they are small - do not allow weeds to establish.
