After several days of spring-like temperatures, our Pacific Northwest weather has made a u-turn back to winter. Well, around here that means the east wind is howling, bringing low temps to near freezing. But, when you factor in the 15 to 30 mph winds, that makes us feel considerably colder. With our friends in the mid-west and back east enduring much lower temperatures and a fresh onslaught of snow, all I can think about are cold hardy conifers!
Three of my favorite hardy conifers make a beautifully colorful vignette when grouped together in the landscape or in containers. This time of year when many other plants are taking a beating from the bitter cold, these three provide enough color to make anyone smile.
My first selection is the bright, silvery blue, Chamaecyparis pisifera ‘Curley Tops’. This vigorous grower rates within the Intermediate growth range as charted by the American Conifer Society, putting on 6″ to 10″ of new growth per year in my area. ‘Curley Tops’ has a very nice compact form with soft, dense, curly blue foliage. If you would like to slow its growth, it does respond very well to a nice light annual shearing. Naturally growing in a cone shape, if one desired, it could be shaped to the heart’s content.
Chamaecyparis pisifera ‘Golden Mop’ is listed as a dwarf, but keep in mind that it can become large in time. As a young plant, ‘Golden Mop’ will form a broad roundish mound of bright yellow, coarse, tread-like foliage. In time it becomes broadly pyramidal in form and is quite stunning in the garden planted near dark green or blue conifers. Its color takes on a rich golden hue as winter becomes more intense.
Finally, Chamaecyparis pisifera ‘Cumulus’ is a great little miniature with tight coarse green foliage and a form that is reminiscent of those wonderful, fluffy, puff-ball clouds on a warm spring or summer day. Since this one is a true miniature conifer growing close to an inch per year, it is perfect for the container garden too. In fact, if acquired as young plants, all three selections are suitable to be grown in containers for a number of years. Then, as they put on some size, you could place them near each other in the garden for a spectacularly colorful corner. Add more colorful conifers or other companion plants for a display worthy of the finest gardens.
Until next time, stay warm!
