The town where I live had lots of mimosa trees (Albizia julibrissin) in the 1940's, 50's and 60's. Some died to a blight, many were cut down to pave roads, protect power lines and succumbed to the ravages of ice storms and thunderstorms. According to the Forest Service and NC Extension Service, these trees are invasive. And they are to be found here and there. These were seen along a roadside the other day.
Thanks for all your comments and views. It makes me sad too that they’re considered to be invasive. They were probably brought from China or the Orient somewhere they have that style. Wiley is correct. They have beautiful flowers like little feathers.
