- Delairea odorata is a perennial vine that climbs up trees and will reach heights of 16.4 ft. (5 m) in suitable climates.
- The leaves are alternate, broadly deltate to "ivy-shaped", with 5-7 shallow, but sharply pointed lobes.
- Flowers are axillary or terminal cymes, with individual flowers yellow, disk corollas 0.16-0.2 in. (4-5 mm) long arranged in clusters.
- The fruit is an achene about 0.08 in. (2 mm) long, often with a pappus and a "crown" of hairs.
- Ecological Threat
- Delairea odorata has become an invasive species in California, Hawaii, Oregon, New Zealand and Australia. The plant will cover shrubs and trees, inhibiting growth and will also cover ground intensively over a wide area, thereby preventing seeds from germinating or growing. It is native to South Africa.
