Mignonette Vine
Madeira vine
Basellaceae - Anredera cordifolia

What does it look like?

Perennial, climbing, hairless, woody vine with fleshy rhizomes and slender, usually reddish stems with small irregular 'warty' aerial tubers. Fleshy to succulent heart-shaped leaves (2-11 x 2-10 cm) are glossy, clammy to the touch, and arranged alternately on the stems. Slender, drooping flowerheads (18 cm long) of small, numerous, fragrant cream flowers are produced from January to April, but no fruit is formed.

Why is it a problem?

Smothers all plants to medium to high canopy, preventing the establishment of native plant seedlings. Combined weight of aerial tubers can topple small trees. Grows at a moderate rate but forms heavy, long-lived masses that dominate medium to high canopy. Tolerates drought and damp conditions, wind, salt, many soil types, moderate shade and damage.

Control Methods

Physical control

  • Dig out plants, (ensure you get all tubers) any time of the year. Dispose of all tubers, both underground and aerial at a refuse transfer station. Leave stems of the vines to rot away on site.

Herbicide control

  • Drill larger stems and squirt in 5-10mls of 5g metsulfuronmethyl (600g/kg e.g. Escort®) per 1 Lwater, or
  • Clear it off trees you want to keep ensuring no tubers break off and spray the vine carefully with 5g metsulfuron-methyl + 10mls penetrant per 10 litres water.
  • Repeat applications are necessary until all tubers are killed.

Where large underground tubers are not be killed using herbicide, digging and removal will be necessary.

CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
