Description
A scrambling woody shrub to 3 metres (sometimes higher as a scrambling
climber) with distinctive forked leaf venation and purple flush on new leaves. Siam produces clusters of mauve-white flowers in May-June and October.
Methods of Spread
Each seed has a tuft of white hairs that allow it to be transported by wind and water. Seeds will also attach to vehicles, machinery, clothing, footwear and animals.
Health issues and toxicity
Siam weed may also cause skin complaints and asthma in
allergy-prone people. Siam weed contains very high nitrate levels and has been known to effect breeding of stock.
