Tree-of-heaven, Ailanthus altissima

Why this is called tree-of-heaven is a bit of a mystery; stink-tree is a much better name. This is a weak-wooded, fast-growing, weedy, stinking tree that prolifically sprouts from roots and from seed. Its leaves are long compound leaves somewhat similar to ash or walnut but are readily distinguished by their odor when rubbed. Even where there is no large, this species often persists in the understory as small saplings, often connected by a root system. There are both male and female trees, so it is more important to eradicate the females first to break the seeding cycle.

Eradication tips:

Hand-pulling can be effective, but it's necessary to grab the stem as far down as possible, because they will otherwise break off just above ground level. They will commonly re-sprout for several years, however. In fact, if a tree is cut down, it will send up dozens of vigorous shoots from the roots in the immediate vicinity. The stems may also be cut just above ground surface and concentrated herbicide applied to the cut surface.
