Weird Question.....Tree Identification

[purpleinopp]

Wisteria and Ailanthus were what I was going to suggest also. Bradford pear trees can really waft a horrible stink. I'm not good at attaching descriptive words to smells, but without a doubt, those trees stink in some unpleasant way. Paulownia could be the culprit. Some report a honeysuckle scent, some report unpleasantness.

Determining when these bloom in your area to see which coincide with when you detected the odor would be a good way to investigate although flowers don't have to be big enough to be noticeable to waft an odor, good or bad.

Eucalyptus, not hardy in NJ. Hopefully Privet isn't, but not sure. Hideously stinky stuff. The whole world stinks for a few weeks here when that stuff blooms, no escaping it anywhere outside.
