False-acacia Robinia pseudoacacia
|Best Time to See|
A non-native invasive plant.
False-acacia is readily available from garden centres and extensively planted in gardens, as a street tree and in parks. It spreads mainly by suckering.
What's the problem?
Although it is currently uncommon in the wild it is showing alarming signs of spreading in some disturbed habitats (for example on railway lines). Its rapid spread, suckering nature, ability to re-grow when cut down and spiny, impenetrable habit when established means that it is a major cause for concern. In France and Italy the tree is freely establishing in woodlands, much as sycamore has done here. We have the ability to control it in the wild in Britain at the moment, but it has the potential to become a major established pest in the coming decades.
