Groovy...
You already started a thread on this tree. Your email was not dragging it's heels.
So it was, this is the first article I read and took the test for. Not because it's short, either.
When I clicked "tree of the seminar" and say it was a red maple, that kept me glued to the page. Red maples in general, are one of my favorite trees. A few people in southern Oregon here warn against using them a little bit, but I think they just have not "learned the ropes" to plant, establish and preserver these.
One unique benefit I could see stemming from this 'Sun Valley' red maple, would be a decreased need or decreased use of herbicides in relation to seeds, if its truly fruitless.
I'm guessing that the thin bark and potential for sunscald may be a reason not to plant in the north regions in autumn. Did not say why, exactly, but that's the first thing that came to mind.
If that's true, then there could be several options to circumvent that.
Even 'Red Sunset' has strong wood, so if this is as good or better, it should be an excellent multi-purpose tree.
