Tree and plant descriptions

  • American elm

    Ulmus americana
    Elms are loved for their graceful, stately shape, with branches like spreading fountains, and their green leaves that turn gold in fall. Sadly, the American elm can no longer be recommended because it is vulnerable to a devastating pathogen called Dutch elm disease. For cultivars of American Elm that are resistant to Dutch elm disease, see below.
  • American hazelnut

    Corylus americana
    American hazelnut is a thicket-forming native shrub, excellent for naturalizing, woodland gardens and shade areas. Showy male flowers (catkins) add early spring interest, dark green leaves turn a beautiful kaleidoscope of colors in the fall. The nuts mature from September to October, attracting seed-eating birds, such as blue jays and woodpeckers.
  • American holly

    Ilex opaca
    American holly is a broad-leaved evergreen tree reaching 40 to 50 feet high, densely pyramidal in youth becoming more open and symmetrically conical with age. The dark green, elliptical leaves have several spiny teeth along the leaf margin. Plants grow best in low, acid pH soils in part shade. Avoid windy sites. Trees are either male or female and require several to get fruit production.
  • American hornbeam

    Carpinus caroliniana
    The American hornbeam is a native forest understory tree in the Chicago area, making it useful for shady landscapes and naturalized or woodland gardens. New leaves emerge reddish-purple, changing to dark green, then turn yellow to orange-red in the fall, offering a kaleidoscope of color throughout the year.
  • American Sentry® linden

    Tilia americana 'McKSentry'
    The American Sentry linden is reported to have some resistance to Japanese beetle. It is a dense shade tree with heart-shaped leaves and fragrant flowers; this cultivar is particularly symmetrical. This is a cultivated variety of a native plant.
  • American smoke tree

    Cotinus obovatus (syn. Cotinus americanus)
    American smoke tree is a native of North America, but is little used in home landscapes. This small to medium tree produces the same 'smoke' (hairy fruit stalks) as it's Eurasian cousin, smoke bush and also offers excellent fall color.
  • Amur cherry

    Prunus maackii
    Amur cherry is an ornamental tree native to Manchuria, Siberia, and Korea. It has beautiful amber to reddish-brown flaking bark; clusters of fragrant, white hanging flowers in spring; and red maturing to black fruit.
  • Amur maackia

    Maackia amurensis
    Amur maackia is a compact, rounded tree for smaller landscapes. The compound leaves emerge silvery-green in spring changing to medium green in summer. White, spiky flowers appear in mid-summer when little else is flowering and showy, mottled olive-green bark adds to winter interest.
  • Amur maple (Not recommended)

    Acer ginnala
    Amur maple has invasive traits that enable it to spread aggressively. This tree is under observation and may be listed on official invasive species lists in the near future. Review of risks should be undertaken before selecting this tree for planting sites.
