Having just carried out what has become, over the last several years, a regular chore, that is cutting back a specimen of Leucaena leucocephala. As I say we planted this a long time ago thinking it was a fast growing, reasonably attractive tree with its pom-pom flowers. Little did we realise what a mistake that was. It became an absolute nightmare of a plant, seeding itself around profusely and growing out of all control. I have since discovered that it is listed as one of the 100 worst invasive species by the IUCN. Fortunately the tree is planted outside our boundary wall and we have been able to prevent it from seeding by cutting it back before it flowers and sets seed. However the trunk has proved impossible to dig out without demolishing part of the wall, so I have to cut it back to ground level at intervals to keep it in check.
Be warned, avoid this tree at all costs.
