Cryptostegia grandiflora / Rubber Vine
Cryptostegia grandiflora, Rubber Vine - IMG 4990
This species, which is a native of Magagascar, might appear to be an attractive and even desirable plant, but it's made itself far from welcome in Australia, particulalry in northern and central Queensland. It's a fast growing climbing plant that rapidly colonises new territory and that smothers other plants. It's rapid advance across the landscape is extremely difficult to control, and is one of northern Australia's most aggressive environmental weeds.
