I seen these at a local nursery and the foliage is really pretty. It says on the tag that birds like the fruits so I am thinking of planting several of these, but I wonder if it is a long term tree or short lived? I am looking for something long term that grows fast but is not invasive.... any such thing? I loved the purple color leaves on this and that it doesn't get humungous as many trees do. Tag says to 30 ft. Does that sound right?
