What makes a plant popular for winter landscapes in the snowy regions of the globe? Are conifers the sole contestants? Which landscaping plants are automatically disqualified? Which shrubs are best for attracting wild birds? Answering such questions should help generate landscaping ideas for dealing with that Scrooge of the seasons, horticulturally speaking: winter. Our goal is to turn a drab yard into a winter scene worth painting—for that matter, worth looking at while you're snow shoveling.
While evergreen shrubs (including shrubs with golden foliage) and conifer trees undeniably add visual interest to winter landscapes, so do many other plants, such as red osier dogwoods. About the only plants that are disqualified right at the outset are those that lack any appreciable height: no matter how pretty a plant may be, it will add no visual interest to the winter landscape if it lies buried all winter, dwarfed by a blanket of snow. Based on this premise, let's explore ideas to enhance the winter landscape. And let's keep in mind that many landscaping enthusiasts are also bird watchers; so that a plant's ability to attract wild birds will be a consideration.
Characteristics to Look For
A winning plant for winter landscapes will have one or more of the following characteristics:
Surprise and delight your guests with three courses created around the soft, sweet, sensuous, rich, and unexpectedly versatile flavor of the season—vanilla.
■ Contains colorful berries that attract birds for bird watching
■ Readily catches snow in its branches
■ Exhibits a delicate structure
■ Is clad in a bark that is colorful or that has an unusual texture
■ Bears evergreen foliage
■ Has an interesting branching pattern
Popular Plants for Visual Interest in Winter
Let's look at some popular plants exhibiting these characteristics. Conifers take a back seat; their value to winter landscapes goes without saying, so we're limiting their representation to two entries here. The following is a list of popular plants for adding visual interest in winter.
Christmas Holly Shrubs
Evergreen holly is popular due to its striking, year-round foliage and bright berries that attract many bird species. Sprigs of cut holly have long been used in winter holiday decorations. Many evergreen hollies are not hardy enough for far Northern climes, but two of the hardier varieties are:
■ China holly (Ilex meserveae): This is a rounded holly, 8' high by 8' wide, and it is also drought tolerant.
■ Compact inkberry holly (Ilex glabra 'Compacta'): This plant has dark green foliage that resembles that of boxwood shrubs. Its berry is black, not the usual red that we associate with hollies. It reaches a height of 4' to 8'; its width is a bit less than that. You can also grow the similar Ilex glabra 'Densa'.
Red Osier Dogwood
Red osier dogwood (Cornus sericea 'Allemans') is another extremely hardy plant (zones 3 to 8). The May flowering of red osier dogwoods yields white blooms that are followed by white fruit. But red osier dogwood makes this list because of its bark, which ranges in color from red to burgundy. Reaching a height of 6' to 10', the spread of red osier dogwoods is 5' to 10'. A patch of fiery red osier dogwood against a backdrop of pristine snow makes for an unforgettable winter scene.
When planning the winter landscape, don't forget to include at least one tall perennial grass. An ornamental grass with a stately, thin shaft and fluffy coiffure exhibits such a delicate structure that it will doubtless lend a touch of charm to any winter landscape, however, barren otherwise. Plume grass (Erianthus ravennae), which can grow to be as tall as 11 feet (by about 4 feet wide), is hardy as far north as zone 4 (for those of you in hotter climates, it is listed for as high as zone 9).
Bayberry (Myrica pensylvanica) is a shrub with a spreading habit (4' to 6' X 4' to 6'), grown in zones 2 to 8. It's glossy, aromatic foliage complements its waxy, gray fruit. In fact, these unusual berries are widely used to scent candles—if you can get to the berries before the birds do, that is. It is also a drought-tolerant shrub. The birds may like bayberry, but the deer don't, as it's one of the deer-resistant plants.
Compact American cranberrybush viburnum (Viburnum trilobum 'Compactum') yields masses of red berries that serve as a source of food for birds on the winter landscape. A rounded shrub, it bears white flowers in May and June that are followed by red fruit. As a bonus, the shrub offers foliage ranging from red to purple in fall. American cranberrybush viburnum is hardy to zone 2. It grows 4' to 5' high, with a spread of 3' to 4'.
Winterberry holly (Ilex verticillata) is a deciduous holly bush indigenous to wetlands in the eastern half of Canada and the U.S. As stated above, usefulness for attracting wild birds in winter is one of the criteria considered for this list, and the fruit of winterberry will certainly attract birds to your property. Far from being a drawback, its deciduous nature is actually a benefit for the winter landscape. Why would you want leaves to be in the way when you have such gorgeous berries to behold?
A dioecious shrub (as are bayberry and evergreen holly), to ensure fruit production it is best to plant several shrubs together, to increase your chances of finding a male plant to accompany the females.
Three varieties of birch trees lend considerable interest to the winter landscape, two of them (the second and third entries below) because of their bark.
■ Young's weeping birch (Betula pendula 'Youngii')
■ Paper birch (Betula papyrifera)
■ Yellow birch (Betula alleghaniensis)
Yews are renowned for being plants in our Christmas traditions. These conifers bear evergreen needles and bright red berries. But keep children away from both the foliage and the berries of these poisonous plants; the seeds and needles are quite toxic.
Are you surprised to see eastern hemlock trees (Tsuga canadenesis) included in a list of landscaping plants? You may think of them first and foremost as tall trees (60' or more) that you encounter out in the woods. But plant developers have bred cultivars that are more shrub-like, which are well-suited for use in hedges, etc. Shear them to keep them at the desired height. Whether used in hedges or as specimens, these evergreen conifers will help give your winter landscape some much-needed visual interest.
Viking Black Chokeberry
Like winterberry holly, Viking black chokeberry (Aronia melanocarpa 'Viking') tolerates poorly-drained soils. Like American cranberrybush viburnum and barberry, this shrub provides foliage that ranges from red to purple in fall, making it a two-season standout. Viking black chokeberry is hardy to zone 3. As with all the berries mentioned in this article, chokeberry berries serve as emergency food for wild birds. They're not the birds' first choice—they are astringent or otherwise unpalatable, which is why they stick around so long—but when the birds get desperate, these plants are their salvation. Its white flowers in May yield to purplish-black berry clusters. It grows to a height of 3' to 5', with a spread of 3' to 5'.
Plants to Avoid
The final two shrubs didn't make the top 10 above. We mention them simply because they used to be popular for providing winter scenes in the yard: Japanese barberry shrubs and winged euonymus shrubs. Both, however, are invasive plants, so seek alternative components for your winter scenes where possible.
Japanese barberry (Berberis thunbergii) is a rounded shrub with thorns, hardy to zone 3. It ranges between 4' and 6' both in height and spread. Its leaves put on a color show in autumn, changing to orange, then to reddish-purple. Small yellow flowers in spring are succeeded by oval, red berries. These fruits last well into winter, thus serving not only as components for winter scenes but also as a source of food for wild birds. As an alternative, try cotoneaster plants.
Winged Euonymus Shrubs
Winged euonymus (Euonymus alatus), also called "burning bush" (height 10' to15', spread 10' to 15'), is grown in zones 4 to 8. For the purposes of winter scenes, the common name, "winged euonymus" is apropos. Indeed, the Latin, alatus, does translate to "winged." But in addition, it is the "wing" or corky flap of bark running along the edges of its stems that is responsible for this plant's popularity for winter scenes. Because of this corky protrusion, winged euonymus catches and holds snow more readily than most plants, affording glimpses of sparkling winter scenes.
