Thomas J,
I don't know if it's strange or not but...... it probably is, it's a strange world. They come in all different flavors.
Ulmus parviflora click on the cultivars list.
This one seems to have a yellow color to it.
I live in a very cold climate and this fall the leave on the chinese elms just turned brown and fell off.
Most years mine turn purple though. The seed source of mine came from a tree from in Madison, Wisconsin.
Ulmus parviflora isn't even supposed to be hardy here but the ones I have been growing are very hardy. They are what's left of a bag of seeds I got from the director of the Arboretum in Madison.
I just read M. Dirr's book and officially they turn yellow to reddish purple so I think we're covered.
I like the shape of this one:
Ulmus p "Alee"
