Legal Status: Unwanted Organism - BNZ
Status in New Zealand: Established
Organism: Land plants


This is a vigorous evergreen high-climbing vine which grows to 6 m. Stems are long and angular with spiralling tendrils. Leaves are very thin and five-lobed almost to the base, each lobe being 3-8 cm long and narrow. Hanging whitish-purple flowers (6-9 cm in diameter) with purple filaments are produced from December to April. Flowers are followed by hanging round fruit (3-5 cm in diameter) that ripen from green to yellow. The fruit have small amounts of inedible pulp, and contain silver-brown seeds (4 mm long).


This plant smothers the canopy, can strangle host stems and prevents the establishment of native plant seedlings. It appears in light wells away from the parent plant.
