Yes while they are good for hummingbird and butterfly attraction, and the shade value thing, but don't plant this in southern VA unless you want them sprouting everywhere...EVERYWHERE! We planted just One on our 2 acre property from some seeds from a tree we noticed on the side of the road--not realizing what it was at the time, simply that it looked pretty. It grew to quite a large size, then died and had to be removed a couple of years ago, and still even today there is not a single place where we are not fighting to keep them from taking over everything. Our former rose bed is now a Mimosa bed! And good luck trying to remove this plant by the roots, even at just 2 inches tall, we have found them to have up to a 12 inch long taproot that makes removing them by pulling simply impossible. Definitely not on my favorites list, lol.
The closest mimosa tree that I've been able to locate in our neighborhood is about 1/4 to 1/2 mile away from us, and we STILL have tons of seedings to yank out every year. Attractive they may be, but lordy, what pests they are.
