Tree of heaven

(Ailanthus altissima)

A non-native invasive plant.

This deciduous tree, originally from China, is very widely planted – in gardens, streets, parks and public spaces. As well as getting into the wild by seed dispersal from growing trees, it is also spread by the dumping of excess material.

What's the problem?

Like rhododendron, this plant prevents other vegetation from growing in the surrounding area by releasing toxic compounds. Attempts to control it by cutting result in more vigorous growth.

It is not yet known to be causing problems at sites of botanical interest here, but in some countries where it has already caused so many problems, it is called the 'Tree of hell'.
