The list of trees with interesting bark for winter interest continues.
Oxydendrum arboreum, sourwood—brown, deeply furrowed and ridged bark
Parrotia persica, Persian parrotia—exfoliating, multicolored patchwork bark
Philadelphus coronarius, mock orange—reddish-brown, exfoliating
Physocarpus opulifolius, common ninebark—exfoliates in long strips
Pinus bungeana, lacebark pine—patchy exfoliating bark revealing splotches of multi-colored inner bark
Pinus nigra, Austrian pine—dark brown vertical furrows with lighter ridges
Platanus occidentalis, American planetree or sycamore—grey bark exfoliates in patches revealing lighter greys beneath
Platanus x acerifolia, London planetree, Zones 5-8. A cross between the American and Oriental species of planetrees, this one has gorgeous multi-colored bark.
Prunus maackii, Amur chokecherry—rich shining mahogany colored bark with horizontal lenticels; older specimens may exfoliate
Prunus serrula, paperbark cherry—shining red bark marked with horizontal lenticels, exfoliating with age
Pseudocydonia sinensis, Chinese quince—very interesting flaking bark in shades of gray, brown and green
Salix matsudana ‘Tortuosa,’ Peking willow—interesting drooping and contorted branches
Salix melanostachys, black pussy willow—dark black branches in the winter and spring
Sassafras albidum, sassafras—red-brown deeply furrowed bark in mature specimens
Sequoia sempervirens, redwood--fshaggy, fibrous hide on mature trees. Of course, this can be a gigantic tree in the wild and needs plenty of room, so for most of us it will be admired in arboreta or national parks, though there are a few dwarf cultivars out there.
Stewartia koreana, Korean stewartia—reddish-brown to gray flaking bark. This beautiful one at Asticou Azalea Garden, Mt. Desert Island, Maine.
Stewartia monadelpha, tall stewartia—tan bark exfoliates showing cinnamon patches-distinctive
Stewartia pseudocamellia, Japanese stewartia—smooth texture, beautiful pale mottled pattern of pinks, tans, browns, and grays-striking
Stewartia serrata, sawtooth stewartia, Zones 6-9. Stewartias have some of the handsomest bark which makes them outstanding specimens for winter interest. S. serrata's reddish bark flakes to reveal grays and lighter tan bark beneath.
Styrax japonicus, Japanese snowbell--dark gray-brown bark with irregular breaks with age on muscular sinuous-shaped trunks.
Ulmus alata, winged elm--irregular vertical ridges of shaggy gray bark
Ulmus parvifolia, lacebark elm—mottled, irregular patchwork pattern of grays, browns and reds
Zelkova carpinifolia, Caucasian zelkova--smooth gray bark that flakes off to reveal orange underneath.
