Mile-a-minute is already here but we’re working to get rid of it.
Why it is a pest plant
|Production threat||Environmental threat||Public threat|
Mile-a-minute is an evergreen fast growing vine. It smothers and kills most plants from ground level to medium canopy and prevents the establishment of native plant seedlings. It thrives in bare sites and increases nitrogen in poor soil types, potentially changing the species that can grow there.
It is likely to invade forest margins, coastlines, cliffs, shrublands, rocky and limestone areas.
Seeds drop near parent plants and can be spread by birds. However, the spread of mile-a-minute occurs most often from dumped vegetation or infested soil. Originally from South Africa, there are only a few known locations in the Waikato region.
- Pea-like flowers which can be pink, white, lavender and white or reddish purple.
- Flowering occurs over a long period – July to January.
- Boat-shaped seed pods, similar to pea pods, 3-4cm long.
- Pods can be found on the vine all year round.
- Small, clustered berry-like fruit.
- Fruit is initially green but ripens to a juicy purple-black colour.
- One small pale seed in each fruit. Seeds are attractive to birds.
- Leaves are made up of three triangular/heart-shaped ‘leaflets’.
- Leaves measure about 2.5-5.5cm long.
- Leaf stems are moderately hairy and woody towards their base.
