Comments: Mimosa has been planted as an ornamental tree in many locales. It tends to be a short-lived tree that’s considered an invasive species in some areas. Unlike other exotic Albizia species which are diffuse porous, Mimosa tends to be semi-ring-porous, especially when grown in temperate regions.
