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

  • Hand-pull small plants any time of the year, ensuring all stem and root fragments are dug out. Dispose of roots at a refuse transfer station and leave the tops 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 litre water, or
  • Clear it off trees you want to keep and spray the vine carefully with 5g metsulfuron-methyl + 10mls penetrant per 10 litres water, or
  • Repeat applications are necessary until all tubers are killed.
