It’s a male cultivar (no seeds or boxelder bugs), it has an attractive reddish leaf colour (year round) and is a medium size tree. It is relatively fast growing so I suspect in the long run it might have some of the weak wood and decay issues as the Acer negundo species, but in the right place I think it might be a good tree choice. I have been impressed with this tree in parking lot islands and in sidewalk cutouts where there is very limited soil and harsh conditions that would kill most trees. At a Canadian Tire parking lot near my house I have watched some of these trees over the last 8 years growing in very small volumes of soil and as a result they are growing quite slowly, but they don’t seem to be showing any symptoms of decline or stress and they aren’t lifting any asphalt (not yet anyway) in spite of the lack of any root barriers. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>One tree that I’ve been impressed with as an American elm alternative is Zelkova serrata.
