Madeira vine (Anredera cordifolia)
Madeira vine (also called lamb’s tail) is an invasive vine
from South America. Originally it was introduced to Australia as an ornamental
plant in gardens. It is no longer planted but people in older gardens could
still have it growing over sheds or along fence-lines. It has become an
environmental weed, locally and Australia-wide, blanketing and smothering both
shrubs and trees. Once it is in flower it is very obvious throughout
Helensburgh and surrounding areas. It is listed as a Weed of National
Significance.
Madeira
vine is a twining vine with wide, fleshy, heart-shaped leaves that are 2 to 15
cm long, with fragrant, cream-coloured flower spikes up to 30 cm long in
March/April. As stems mature they develop aerial tubers which can become very
large.
Dispersal:
Madeira vine spreads via the aerial tubers which drop to the ground and form
new plants, and also by root tubers. These tubers can be washed down creeks and
drainage lines during heavy rain. The tubers can be viable for many years. The vine
may also be spread in Council green waste, or dumping of garden waste in
bushland.
Removal:
Large vines which are smothering trees may need herbicide treatment. Pulling at
the vines means that the aerial tubers drop on the ground. Smaller plants can
be hand removed. All tubers and tuberous roots need to be removed. All parts of
Madeira vine should be put in your red bin. Alternatively, put it in a black
plastic bag and leave in the sun for some months, depending on the season. For treatment with herbicide, the 'stem-scrape' method is best. This method is also called bark-stripping or stem-painting. Stem-scraping is used for plants and vines with aerial tubers, or where underground tubers and roots are in a difficult-to-get-to place. A sharp knife is used to scrape a very thin layer of bark from a 15–30 cm section of the stem. Herbicide is then immediately applied to the exposed area soft underlying green tissue.
