German ivy
Asteraceae - Delairea odorata

What does it look like?

German Ivy is a scrambling or climbing vine that can reach heights of 5m. It has thin, weak, green stems and thin, soft, glossy leaves that are ivy-shaped and clammy to the touch. It is in the same family as ragwort, with similar yellow flowers from May to October, that go on to form fluffy seeds.

German ivy grows well in open environments such as forest margins and scrub. It is also found on roadsides and in quarries, farm hedges, wasteland and house gardens. 

Why is it a problem?

German ivy is fast-growing and has a dense, smothering habit. It prefers open, damp sites but is partially tolerant to shade and drought and will grow in most soil types.  It produces large number of wind-blown seeds and can also regrow from fragments of stems and roots. Natural areas that are at risk of invasion by German ivy include forest margins, coastal communities and the edges of wetlands.

Control Methods

Physical control

  • Hand pull or dig out small plants and dispose of roots at a refuse transfer station, burn, or bury deeply.

 Herbicide control

  • Most easily controlled at flowering, when highly visible and before seed is produced. Cut stems below waist height, spray below this point with glyphosate (360g/L) 10ml/L knapsack or 2L/100L spraygun or metsulfuron-methyl (600g/kg) 2g/10L knapsack or 20g/100L spraygun.

  • Cut down and paint stump with glyphosate (360g/L) 100ml/L or metsulfuron-methyl (600g/kg) 1g /L.
