The Lacebark Elm tree, Ulmus parvifolia, is a superb tree for urban conditions and should be widely considered for use as a street tree. This deciduous shade tree is a very hardy, tough tree that is capable of withstanding the rigors of harsh climates, poor soils and streetscape situations. The grey bark begins to exfoliate or peel off in small patches as the trunk matures resulting in an interesting combination of mottled colors beneath, including green, gray, orange and brown.
