The texture of tree bark becomes an important element in winter when the shedding of leaves exposes trunks and branches. The variety of colors and textures is fascinating. The bark’s texture may change as the tree matures. The bark of a black locust (Robinia pseudoacacia), for instance, is quite smooth when young, becoming deeply furrowed as it ages. Conversely, a paperbark maple (Acer griseum) will exhibit its flaking, exfoliating characteristics when very young. One of our favorites in the South is crape myrtle (Lagerstroemia indica) with bark that peels to reveal smooth pinkish or grayish bark beneath. Some trees have colored bark, like the famous white bark of the canoe or paper birch (Betula papyrifera), or the dark red stems of a red-osier dogwood (Cornus sericea). Imagine the beauty of a hedge or mass of red-osier dogwood surrounded by snow! Site a tree, such as a river birch (Betula nigra) with its flaking bark, where you can easily admire it as you pass it on a walkway or look out a window.
Acer buergerianum, trident maple—smooth gray bark, fissures and splits with age
Acer griseum, paperbark maple—exfoliating reddish bark, even on young trees
Acer palmatum 'Bloodgood' Japanese maple, interesting dappled grey effect
Acer palmatum ‘Nishiki gawa,’ Japanese pinebark maple--has rough-textured bark resembling pine bark. A good choice for a small specimen tree or bonsai.
Acer palmatum ‘Sango Kaku,’ coral bark Japanese maple—coral color on young shoots
Aesculus californica, California buckeye—smooth silver-gray
Aesculus hippocastanum, common horsechestnut—gray to brown, exfoliates with age
Amelanchier arborea, serviceberry—smooth and grey when young, becoming furrowed with age
Arbutus menziesii, Pacific madrone—grayish brown and splits into longitudinal fissures
Betula lenta, sweet birch—shiny dark reddish brown becoming scaly with age
Betula nigra, river birch—peeling, exfoliating bark
Betula papyrifera, paper birch—famous white bark that peels in thin horizontal strips revealing reddish inner bark. Indians used to make canoes and shelter. Best in Northern zones.
Betula pendula, European weeping birch—whitish when young, becoming mostly dark with age
Carpinus betulus, European hornbeam-- smooth, bluish gray; hard, muscular fluted trunk
Cercis canadensis, Eastern redbud—dark, blackish bark stands out in winter, good foil for the pink buds which pop out directly from the branches. Younger bark looks much smoother and develops this sort of criss-cross pattern with age.
Cercidiphyllum japonicum, katsuratree—the bark becomes shaggy with age on a tree that is beautiful in all seasons. Outstanding specimen tree.
Chionanthus retusus, Chinese fringetree--multiple trunks develop with bark in shades of gray, brown and tan may be furrowed or exhibit exfoliating characteristics.
Cladrastis kentukea, American yellowwood--smooth gray bark with lighter patches giving a striped effect. Similar to American beech.
Cornus alba, Tatarian dogwood—red twigs in winter
Cornus florida, flowering dogwood—rough, gray bark in small blocks, a good identification feature
Cornus kousa, Kousa dogwood--smooth gray bark exfoliates to show tan patches, very different from Cornus florida
Cornus officinalis, Japanese Cornel dogwood—interesting showy bark with gray, brown and orangey patches
Cornus sericea, redosier dogwood—red twigs in winter. Cornus sericea ‘Lutea’, yellow twig dogwood—has yellow twigs in winter.
Cornus wilsoniana, Wilson's dogwood--unusual ghostly patchy white and gray bark. Would be very interesting to use for a white garden in the moonlight
Corylus avellana ‘Contorta’, European filbert, “Harry Lauder’s Walking Stick”—bark is smooth, brown, but stems are fantastically twisted and corkscrewed making for good winter interest
Crataegus marshallii, parsley hawthorn--a small native tree of the southeastern U.S. with patchy, scaly bark that is quite ornamental.
