(Smoothleaf Elm)

A variable elm that often assumes a low-forking, rounded or conical form, Ulmus minor is a medium-sized deciduous tree from Europe, northern Africa, and western Asia. The cultivar 'Umbraculifera' is grown for its dense, symmetrical, broadly globular habit, which lends a formal look to the landscape. A small, low-branched tree, it is sometimes grafted as a standard. The relatively small, oval, glossy green leaves have toothed edges. Fall color is usually a weak yellow. Inconspicuous flowers...

(Chinese Elm, Lacebark Elm)

One of the most outstanding medium-sized trees for the landscape, this variable and disease-resistant East Asian elm bears small, glossy, deciduous or semi-evergreen leaves, which in forms such as 'Burgundy' and 'Pathfinder' turn a good red in fall. Many selections ('Hallelujah' and 'Dynasty' among them) have handsome exfoliating bark mottled with patches of orange, tan, gray, and other contrasting colors. Several dwarf cultivars (including 'Frosty', 'Geisha', and 'Catlin') are also available, characterized...

(Chinese Elm, Drake Elm)

A meritorious selection of a beautiful and disease-resistant East Asian elm, 'Drake' bears small, glossy, deciduous or semi-evergreen leaves that turn shades of yellow and red in fall. Like other selections, it has attractive exfoliating bark, with patches of orange, tan, gray, and green. This tree is an especially good choice for mild climates, where it often holds its leaves into winter. In colder regions, the leaves drop in autumn, and the bark takes the starring role. The flowers and winged seeds...

(Chinese Elm, Dynasty Elm)

A fast-growing, cold-hardy selection of a beautiful and disease-resistant East Asian elm, 'Dynasty' grows relatively rapidly into a medium-sized, vase-shaped tree. Its relatively erect, arching branches do not bow as close to the ground as those of some other selections. Its small, oval, glossy dark green leaves turn a good red in fall. The foliage is evergreen in mild climates. The gray bark exfoliates moderately to display flecks of orange, tan, gray, and green. The flowers and winged seeds appear...

(Chinese Elm, True Green Chinese Elm)

A semi-evergreen selection of a beautiful East Asian elm, this medium-sized round-headed tree retains its small glossy dark green leaves through most of winter in mild climates.

The flowers and winged seeds appear in late summer and autumn and are ornamentally insignificant.

Plant this all-season beauty in full sun in well-drained, humus-rich soil. It tolerates alkaline soil and occasional...

(Siberian Elm)

Hardy, tough, and fast-growing, this small to medium-sized deciduous tree from northern and central Asia was once a popular choice for difficult sites. It is much less frequently used today because of its undistinguished appearance, weak wood, and weedy nature. Of variable habit, it bears small, oval, dark green leaves on upright to spreading branches. The disease-resistant leaves persist late into fall, dropping while still green. Inconspicuous early spring flowers are quickly followed by masses...

(Slippery Elm)

A common elm found across the whole of eastern North American from Quebec, Canada down to Texas, slippery elm is a tough, adaptable species that's quite hardy. Though still sensitive to Dutch Elm disease, it is more prevalent in the wild than its sister species, the American elm (Ulmus americana). It is a deciduous tree of medium height that develops a broad, somewhat vase-shaped crown with age. Wild populations favor lowland sites and floodplains where soils are moist and rich, but trees...
