Add Color into Winter Gardens

Colorado is often pictured as a snow covered winter wonderland.  Although our mountains may have snow from October to May,  the Front Range often sees extended cold and dry conditions.  Here dry means a drab grey landscape in a sea of brown grass.

To beat the blahs,  look to these bright beauties for a winter pop of color.

acer senkaki – Acer palmatum ‘Sango-kaku’ (its Japanese name means “Coral Tower”, formerly Acer ‘senkaki’), is one of the coral bark maples and is one of our favourite Japanese maples since it gives interest and beauty in all seasons of the year. The attractive bright coral-red of the young branches is particularly visible during winter and early spring.

Salix alba ‘Britzensis’

Plants to consider are bloodtwig dogwood (Cornus sanguinea), including the ‘Midwinter Fire’ and ‘Winter Beauty’ cultivated varieties; redosier dogwood (C. sericea); and yellowtwig dogwood (C. s. ‘Budd’s Yellow’), which has yellowish stems. Another option is coral embers willow (Salix alba ‘Britzensis’). These plants can be planted separately or mixed together, for a tapestry of winter color.

Regular pruning in late winter before new growth resumes keeps these plants vibrant. For the dogwoods, cut about a third of the oldest stems back to the ground to encourage new, more colorful stems. It is best to cut coral willow stems completely to the ground each year.

Evergreen doesn’t mean “ever the same.” Make use of the evergreen shrubs that are often forgotten. These include Boxwood (Buxus spp.), Cotoneaster (Cotoneaster spp.), Broom (Cytisus spp.), Euonymus (Euonymus spp.),Firethorn (Pyracantha spp.), and Yucca (Yucca spp.).

emember that many perennials have evergreen foliage (although “evergreen” in some cases can mean more red or purple than green). These include Hardy yellow iceplant (Delosperma nubigenum), Candytuft (Iberis sempervirens), Pine-leaf penstemon (Penstemon pinifolius), Fleeceflower (Polygonum affine), Lavender cotton (Santolina chamaecyparissus), Stonecrop (Sedum spurium), and Partridge feather (Tanacetum densum). The following images reflect thoughtful plant choices that provide a variety of color and textures.
