Tree and plant descriptions

  • Chinese silver grass

    Miscanthus sinensis
    Chinese silver grass is known by many names, including maiden grass, eulalia, Japanese silver grass, and miscanthus. It has been used widely in many landscapes and a great number of cultivars have been developed. Of the numerous cultivars, most are hardy to zone 5 , while some are hardy to zone 4. This grass should be used with caution. In some parts of the United States, this grass has spread into natural areas by seeding and is considered invasive in those areas.. Review of risks should be undertaken before selecting this grass.
  • Chinese witch-hazel

    Hamamelis mollis
    In very early spring, before the leaves unfurl, Chinese witch-hazel blooms a deep yellow with a tinge of red on strap-like, crinkled flowers. Flowers have a spicy-scented fragrance. The new foliage is yellowish-green, deepening to medium green over the summer and turning buttery yellow in fall.
  • Chinkapin oak

    Quercus muehlenbergii
    Chinkapin oak is native to the Midwest, where it is often found as a specimen planting or as a grouping of tree for parks and large areas. Chinkapin oaks perform well in alkaline soils. Young trees retain a pyramidal to oval habit with a pale gray, scaly ridged central trunk. As trees age, the crown becomes more rounded.
  • Climbing hydrangea

    Hydrangea petiolaris, (syn. Hydrangea anomala ssp. petiolaris)
    Climbing hydrangea is a woody vine that clings and climbs by attaching itself with tiny rootlets to a wall, trellis or other support. In early July, it has flat, lacy clusters of fragrant small white flowers that show up well against the glossy green leaves.
  • Cockspur hawthorn

    Crataegus crus-galli
    Cockspur hawthorn is a Chicago-area native that provides beautiful flowers in spring and persistent fruit in fall and winter. This species should be used with care as it has long thorns and is prone to disease. White flowers in the spring, persistent red fruit, and the orange-red fall color of this Midwestern native make it a nice addition to the four-season landscape.

    Ulmus 'Morton Stalwart'
    This fast-growing cultivar is extremely tolerant of drought and cold. The COMMENDATION™ elm is resistant to Dutch elm disease (DED) but moderately susceptible to insect problems, notably elm leaf beetle, Japanese beetle, and gypsy moth. Use along streets and in large yards. The Morton Arboretum introduced this cultivar through Chicagoland Grows®.
  • Common Bleeding Heart

    Lamprocapnos spectabilis
    Plant advice from The Morton Arboretum: Common bleeding heart is an early-blooming perennial for shady sites. The delicate, pink heart-shaped flowers hang on long arching stems.
  • Common Boxwood

    Buxus sempervirens
    Common boxwood is a broadly rounded evergreen shrub or small tree. Native to Europe, Asia and Africa found in open woodlands and rocky hillsides. A popular ornamental evergreen used as hedges, borders and topiary. Named because wood was popular for making boxes and cabinets.
  • Common buckthorn (Not recommended)

    Rhamnus cathartica
    Common buckthorn is an invasive plant in Illinois and should not be planted. It forms dense thickets and reproduces very freely, crowding out other plants and disrupting ecosystems in forest preserves and other natural areas. In woodlands it can completely replace existing understory plants, including native wildflowers.
  • Common Chokecherry

    Prunus virginiana
    A large deciduous shrub or small, 20 feet high, understory tree often forming a dense colony. Slender twigs form a oval to rounded crown. Clusters of drooping white flowers are followed by dark purple fruit. Native throughout most of the U.S. but difficult to find in the nursery trade.Susceptible to many insect and disease problems.
