Description:
Originating from China and Japan, Japanese Honeysuckle is a vigorous, fast growing climber. Found in moist gullies.

Thin green stems, which root at the nodes and thicken and grow woody with age. Leaves are usually lobed or toothed.

Small yellow cream to white flowers with a pink tinged tube. Flowers occur in pairs in spring and autumn.

Small shiny black berries occur in autumn.

Dispersal:
Rapidly forms a blanket over shrubs and low canopy trees, blocking light and breaking branches leading to habitat loss.

Impact on Bushland:
Tolerant of shade and filtered sun, Impatiens has naturalised along many urban watercourses. Its brittle stems are easily broken and carried downstream by floodwaters.

Control:

Manual: Honeysuckle grows intertwined with other plants, making it difficult to remove.
  Do not pull out of trees and shrubs because of the damage likely to be caused.
  Dig or rip out, removing as much root as possible.
  Alternatively, stem scrape and paint with a neat glyphosate-based product.
Chemical: Please contact your local control authority for advice on chemical control.
