Tree and plant descriptions

  • Heart-leaved foamflower

    Tiarella cordifolia
    Plant advice from The Morton Arboretum: This dainty perennial earns its name from the delicate clusters of white flowers that rise above the almost maple-like foliage. This is a good plant for shady gardens.
  • Hedge Maple

    Acer campestre
    Plant advice from The Morton Arboretum: Hedge maple is a broad-rounded tree that is useful as a specimen or, in groups, as a hedge. It can tolerate part shade, especially when young, and prefers moist, well-drained soil. It is relatively salt-tolerant, so it can be used near sidewalks and driveways. The leaves turn greenish yellow in fall.
  • Higan Cherry

    Prunus subhirtella
    Plant advice from The Morton Arboretum: Higan cherry is a fast growing, intermediate-sized tree known for its early pink to white flowers in spring. The weeping form is most popular in the nursery trade.
  • Hill's Oak

    Quercus ellipsoidalis
    Plant advice from The Morton Arboretum: Hill's oak, a Chicago region native, is very similar in appearance to pin oak, but has the advantage of tolerating higher soil pH. This means that the chlorosis (yellowing) that is common in pin oak is not a problem for Hill's oak. Hill's oak can be used in parkways and has excellent fall color.
  • Hinoki-cypress

    Chamaecyparis obtusa
    Plant advice from The Morton Arboretum: Hinoki-cypress has dark green needles on graceful spreading branches that droop at the ends and attractive red peeling bark. A number of dwarf and compact cultivars add accent to the garden.
  • Hybrid leatherleaf viburnum

    Viburnum x rhytidophylloides
    Plant advice from The Morton Arboretum: This plant is a large shrub that makes a good screen. Does not always fruit well unless another viburnum is close by to serve as a pollinator. This hybrid results from a cross between Wayfaringtree and leatherleaf viburnum.
  • Hybrid witch-hazels

    Hamamelis x intermedia
    Plant advice from The Morton Arboretum: A number of hybrids have been bred between Chinese witch-hazel (Hamamelis mollis) and Japanese witch-hazel (Hamamelis japonica). These large shrubs have interesting confettilike flowers, usually in shades of yellow to red, in late winter or very early spring before the leaves appear.
  • Inkberry

    Ilex glabra
    Plant advice from The Morton Arboretum: Inkberry is a type of holly. The flowers are not showy, but the black fruits can be seen well into winter.
  • Ironwood

    Ostrya virginiana
    Plant advice from The Morton Arboretum: A dainty but tough under story tree with beautiful birch-like leaves, grayish-brown flaky bark, fine-textured drooping branches, and attractive hop-like fruits. Ironwood is considered one of our toughest native hardwoods and is not only ornamental but resistant to many disease and insect problems. Excellent tree for shady or naturalized landscapes.
  • Jack Pine

    Pinus banksiana
    Plant advice from The Morton Arboretum: Jack pine is very hardy and well suited to northern climates. It can be used in windbreaks.
