Ulmaceae
Ulmus pumila
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 of round papery seeds, which scatter and germinate over a wide area. This tree is notorious for losing branches to wind and winter precipitation.
This sun-loving tree grows well in most soils and tolerates high pH, bitter cold, and moderate to severe drought. It is also resistant to Dutch elm disease. In its best forms, such as 'Dropmore' and 'Park Royal,' it makes a good choice for areas with climates too harsh for most other trees. It can also be used for bonsai. It is listed as an invasive plant in many regions.
