A beautiful tree, see the mass planting at the North Carolina Arboretum in Asheville.

I planted one in SE Michigan, it did very well for three years putting on at least 6 feet of growth and branching out very well. Unfortunately it died last winter. I don't think it was the cold because this winter was milder than the previous ones. It had mysteriously received a large wound low on the trunk the season before last (my kids swear they know nothing about it), and I suspect that weakened its constitution.

This cultivar is supposed to be Dutch Elm resistant.

Beautiful bark, much like a Stewartia, except the 'plates' of color are often outlined with orange lenticels. Easily the best feature of the plant.

The leaves are also smaller than other Ulmus species, so it casts lighter, dappled shade.
