General description

Vine climbing to 6m by curled tendrils. Leaves cucumber like, thin, 15 x 15cm. Flowers tubular, to 2cm long coloured whitish with green stripes. Dioecious with male and female flowers on separate plants. On female plants these are followed by 1 cm berries, red when ripe. Aerial shoots die back in winter, large tubers send up new shoots each spring.

Terrestrial. Disturbed and open forest, shrubland, and stream edges.

Tuber fragments via water, soil disturbance, garden refuse. Seed dispersed by birds.

Like old man's beard, it can smother trees and shade smaller plants. It is easily dispersed and its tubers are hard to find and destroy.

Site management

Follow up tuber treatment probably necessary for 2-5 years until eliminated.

Recommended approaches

2. Cut tubers and apply Vigilant gel to all cut surfaces. Re-cover tubers (it may necessary to cut and apply gel to more than 1 part of tuber for very large or 'odd' shaped tubers).
3. Cut tubers lengthwise and swab with herbicide, spring-autumn (5g metsulfuron/L or 200ml Tordon BK/L)
