Lace-bark Elm. One of the nicest of Elms, this species has beautiful dark shiny green leaves which rarely discolor from mildew. And my experience has been that it is resistant to Elm Leaf Beetles. It develops into a medium size tree with a round crown and arching branches. It has been used extensively in downtown Augusta, GA as a street tree. Six feet by six feet sections were cut out of the sidewalk to plant this selection and they have performed remarkably well, making what was an unlivable situation most tolerable. The fall color is a not so spectacularly yellow. With its patchy exfoliating bark, this is truly one of the great landscape trees for America. Please do not confuse this species with the much more inferior U. pumila, Siberian Elm, which starts to fall apart before it gets anywhere near maturity and is also susceptible to the Elm Leaf Beetle.
