This article, written by MGNV member Mary Free in December 2012, is worth a repeat. Appreciating the winter garden makes for a happier all-season gardener!

Herbaceous Plants

As annual flowers succumb to freezing temperatures and many perennials enter a dormant period, one green plant still covers the ground in the woodlands and shade gardens: Polystichum acrostichoides. Also known as Christmas fern, its graceful, finely textured fronds often are used as a seasonal decoration.
An eastern US native, Christmas fern grows in a circular clump with its arching fronds reaching 1’-2’ high and wide. Although it prefers part shade and moist, well-drained soil, it can tolerate more sun with enough moisture as well as drier soils in full-shade. For year-round interest, grow this fairly low-maintenance fern in a woodland or Japanese garden, under trees, en masse, as contrast to shade bed perennials or for erosion control.

Woody Plants

Now that deciduous trees are bare (except for those, like some oaks, hornbeam and beech, with marcescent foliage—dead leaves that remain on the branches through winter), the conifers and hollies that were the backdrops of summer take center stage. Clothed in varied hues of green, their scaly, needlelike, smooth or glossy foliage is accented with cones or berries. However, do not dismiss so readily the defoliated deciduous tree or shrub. The aesthetic quality of its bark (as well as that of conifers) is often overlooked in favor of foliage, flower and fruit. Yet, for one quarter of the year or more, its bark and shape are on conspicuous display.
Though a tree may exhibit its beauty through flower and foliage, its character is revealed with its bark. Who cannot marvel at bark and branches that are smooth or furrowed or peeling or shiny or colorful or mottled or striped or contorted? For a specimen tree prominently featured in the landscape, the quality of its bark may be especially important to ensure four-season interest. So when selecting a new tree for your property, in addition to a tree’s habit (cold-hardiness, heat and drought tolerance, size, rate of growth) and the site conditions (soil type and ph, moisture, sun/shade), be sure to take into account the texture, color and shape not only of its foliage and flowers but of its trunk and branches as well.
Some trees/shrubs to consider for their unusual or stunning bark:
• Those with smooth bark. Natives: Carpinus caroliniana, American hornbeam (blue-gray bark remains smooth even as tree ages); Fagus grandifolia,* American beech; and Hamamelis virginiana, witch-hazel (smooth gray to gray-brown bark; yellow, spider-like flowers mid to late fall). Non-natives: Fagus sylvatica, European beech. (According to Virginia Tech, it is it better adapted to Virginia growing conditions than the native American beech.)
• Those with deeply furrowed or plated bark: Natives: Diospyros virginiana, common persimmon (gray-brown, young bark with orange in fissures; darker, older bark with “square scaly thick plates” described by Virginia Tech as “reminiscent of charcoal briquettes (very unique)”); and Juglans nigra, black walnut (dark brown bark deeply ridged in a diamond-like pattern.)
• Those with peeling or flaking bark. Natives: Betula nigra,* black birch (variable bark with some that exfoliate horizontally in curly sheets); Betula papyrifera, paper birch; Platanus occidentalis, American sycamore (camouflage-color bark that drops with regularity along with fruit and foliage); and Stewartia spp. Non-natives: Acer griseum, paperbark maple; Cornus kousa, Kousa dogwood; Stewartia pseudocamellia, Japanese stewartia (exfoliating older, gray bark reveals lighter patches of cream and orange underneath); and Pinus bungeana, lacebark pine (bark mottled in irregular patches of brown, rust, green and cream).




• Those with red/bronze stems/bark. Hybrid: Acer x conspicuum ‘Phoenix,’ Phoenix maple. Non-natives: Acer palmatum, Japanese maple (red twigs); Maackia amurensis, amur maackia; Pinus densiflora, Japanese red pine (orange-red stems and young bark peel in thin scales; older bark turns gray, developing plates); Prunus spp. (reddish to red-brown to bronze bark); Salix integra ‘Hakuro-nishiki,’ Japanese dappled willow (new stems turn red in winter); and Syringa reticulata (formerly S. amurensis japonica), Japanese tree lilac (shiny, cherry-like, reddish-brown bark).
• Those with striped bark: Native: Acer pensylvanicum, striped maple (smooth, young bark gray-green with white longitudinal stripes; bark ages to a reddish-brown). Non-natives: Acer davidii, David maple (young branches turn red in winter; older bark shiny and green with purple-red highlights and jagged white lines) and Acer tegmentosum, manchustriped maple (striking white vertical stripes on light green bark, but susceptible to Nectria canker).


• Those with contorted shapes. Native: Acer circinatum, vine maple (greenish bark remains smooth even as tree ages; often covered with lichens). Non-native: Corylus contorta, Harry Lauder’s walking stick.
So the next time you walk by a naked tree, stop and take a closer look. Just as flowers may tempt our noses, bark may tempt our tactile senses. You may be pleasantly surprised or even amazed by what you see and feel.
