Native to Burma and India, elephant ear vine is a perennial woody vine that can smother trees. It has been recorded as a weed in Hawaii, and is reported to have naturalised in a number of countries. Elephant ear vine is commonly used as an ornamental garden plant. There is a risk that it may invade rainforests and open eucalypt woodland in Queensland.
Elephant ear vine is a restricted invasive plant under the Biosecurity Act 2014.
- Perennial woody vine climbing up to 10m high.
- Stems and leaf undersides have dense, white downy hairs.
- Leaves are large, heart-shaped, up to 30cm across.
- Flowers are pale pink/white, trumpet-shaped, with dark pink/violet centre 5cm in diameter.
- Berries are round, white.
- Prefers tropical and subtropical regions of Queensland.
Distribution in Queensland
- Found at numerous locations across coastal north and central Queensland.
- Flowering occurs mainly during spring and summer
- Smothers trees, including rainforest and open eucalypt woodland.
How it is spread
- Berries are dispersed by fruit-eating birds.
- Dig up isolated plants and small infestations, making sure to remove all roots and stem fragments.
- No herbicide is currently registered in Queensland; however, an off-label use permit (Permit No. PER11463) allows use of various herbicides for control of environmental weeds in non-agricultural areas, bushland, forests, wetlands, and coastal and adjacent areas.
See the Elephant ear vine fact sheet (PDF, 302KB) for herbicide control and application rates.
- No known biological control agents.
- Elephant ear vine is a restricted invasive plant under the Biosecurity Act 2014.
- It must not be given away, sold or released into the environment without a permit.
- The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. This is called a general biosecurity obligation (GBO).
- At a local level, each local government must have a biosecurity plan that covers invasive plants and animals in its area. This plan may include actions to be taken on certain species. Some of these actions may be required under local laws. Contact your local government for more information.
