Ailanthus

Ailanthus is a naturally nonnative occurring tree in Connecticut. 
== AKA- ==
Tree of Heaven
== Description- ==
A large, fast growing tree. The Ailanthus is also a compound leafed tree. They are often confused with the Black Walnut. While Ailanthus doesn't typically "invade" they are more than capable of doing so, and will take over minimally controlled areas first. Ailanthus very unique as it can thrive in areas most trees wouldn't. Ailanthus trees are known to be able to grow from under houses, buildings, and even in concrete with minimal dirt. The general rule for these trees, is that if there's enough soil to host the tree's infant years, the tree will thrive there for along time. I see a lot of these trees growing in close proximity with buildings. 
Ailanthus grows incredibly fast. While they grow normally pretty fast, at 2-4 feet per year, I've seen specimens grow up to 7 feet in a single year. Pull them up early, because they grow FAST. Only 1-2 year olds can be pulled by hand. Anything else has to be cut. And Ailanthus doesn't give up. It will keep sprouting several times. 
A good identifying factor is its big clusters of flowers in Summer, and seedpods in the fall. These pods are often on the trees through winter. If the seeds are not harvested, they will go distances with the March winds. Seeds can land several feet or hundred feet from the parent tree. Their smooth bark is also a pretty big giveaway, as Walnut and Hickories have ridged bark. Leaves naturally have a stinky odor, that displeases many. I as a nature guy don't mind the smell of Ailanthus leaves, in fact, I find it soothing. Walnuts have spicy scent, Ailanthus is much more like peanut butter. Its been awhile since the Ailanthuses here were in leaf. (Its February). Ailanthuses leaf out, rather late, sometime in May or even June. 
Ailanthus is a colonizer, which means it can grow in huge groups. 
Ailanthus is native of China. The tree was brought over for its quick growth habits. Nowadays its generally almost everywhere.
