Tree and plant descriptions

  • 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.
  • Japanese barberry

    Berberis thunbergii

    A common sight in yards and gardens throughout eastern North America, this Asian shrub is invasive and should not be planted. Growing three to six feet tall, it is most easily identified by its small, rounded leaves, spiny stems, and red berries that develop in summer. Birds and rodents eat the fruits and distribute the seeds widely. Its branches form roots when in contact with the soil.

  • Japanese flowering crabapple

    Malus floribunda
    Plant advice from The Morton Arboretum: A small ornamental tree known for its showy, bright pink buds that open to fragrant white flowers. Japanese flowering crabapple has an irregular, spreading branch habit as it ages, showy, persistent yellow-red fruits, and good disease resistance. Use as a specimen tree, in small groups, or a mixed border.
  • Japanese hydrangea vine

    Schizophragma hydrangeoides
    Plant advice from The Morton Arboretum: Japanese hydrangea-vine is an excellent vine for wood or stone fences, walls, and arbors. It attaches to hard surfaces by root-like holdfasts. Cinnamon-brown bark and large, white lace cap flowers in late June add to the beauty of this climbing vine.
  • Japanese kerria

    Kerria japonica
    Plant advice from The Morton Arboretum: Japanese kerria is a lovely 4 to 6 feet high shrub with upright to finely textured arching stems. Plants are especially attractive when abundant bright yellow flowers open in the spring. The bright green, arched stems add winter interest in a naturalized garden and makes an excellent choice for perennial shade borders.
  • Japanese Spirea

    Spiraea japonica (syn. spiraea x bumalda)
    Plant advice from The Morton Arboretum: A favorite of many gardeners, spirea has a wide range of sizes and cultivars. The dense, compact habit, large clusters of late spring and summer flowers in pink or white, and the excellent fall color provide many seasons of care-free enjoyment in the landscape.
  • Japanese tree lilac

    Syringa reticulata ssp. reticulata
    Plant advice from The Morton Arboretum: Japanese tree lilac is larger than the shrub lilacs and it blooms a little later. It produces large clusters of small creamy white, fragrant flowers.
  • Japanese White Pine

    Pinus parviflora
    Plant advice from The Morton Arboretum: Japanese white pine is a dense, slow growing evergreen with a smaller stature which makes it an excellent specimen for small landscapes or space restrictions.
