Deciduous shrub or small tree < 7 m tall. Stems are grey/green and hairy or red/dark purple and smooth. Leaves are obovate and < 7 x 3.5 cm. Catkins are cylindrical and appear before leaves.
To help protect our environment:
Wet habitats, wetlands, riparian margins, ponds, lakesides, wet areas behind coastal dunes.
Seeds dispersed by wind. Vegetative spread from suckering and stem fragments, dispersed by water.
Forms dense thickets, causing blockages, flooding and structural changes in waterways. Affects native vegetation through competition, shading and altered hydrology.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Do not attempt to undertake control of this species on Aotea/Great Barrier Island group. Please report to Auckland Council if seen on Aotea/Great Barrier Island group.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
