|Botanical Name||Anredera cordifolia|
|Origin||Tropical S. America|
DescriptionStems climbing slender and often reddish. Leaves slightly succulent, shining, broadly oval shaped, up to 110 mm long with small irregular shaped tubers where they join to the stem. Long hanging racemes of small white, fragrant flowers to 180 mm long, January to April. The stem tubers help distinguish this species.
Where is it found?Coastal localities, wasteland, especially shrub covered areas such as coastal gullies.
Why is it a problem?Smothers other vegetation and is a nuisance when it spreads away from roadside dumps and neglected gardens.
How does it spread?Cultivation escape. Spreads freely via pieces of rhizome and stem tubers. Fruit is not formed in New Zealand.
How do I get rid of it?
Remove ground tubers and aerial tubers and dispose of at an approved disposal site.
The preferred option is to burn all tubers on site. If removal is necessary be sure not to drop any bits on the way.
Glyphosate and Penetrant or Triclopyr (Grazon) + Penetrant applied to plants and tubers as soon as green sprouts have two or four leaves on each sprout.
This vine is very hard to kill with herbicide because of its tubers. Plants will be defoliated and the nearest tuber killed but will resprout from the next section of the tuber. Remove every tuber from the trees and ground. Spray as above and monitor closely for regrowth and then spray again. It is important that the second and subsequent sprayings be just as soon as regrowth from the tuber has sufficient leaf to convey herbicide to the tuber. If the leaves are allowed to grow for a longer period new tubers will be formed underground. To control large infestations growing over disirable plants. Cut aerial vines and spray all foliage below cut level.
The tubers may be further distributed by washing down stream or even along the coast in the sea.
Also known as mignonette vine.
This plant is prohibited from propagation, sale and distribution within New Zealand!
