You wouldnt pay much attention to Blood Twig Dogwood in spring and summer. The ordinary green foliage is attractive enough, but it does not sing Here I am!”. It’s not until autumn, when Cornus sanguinea Arctic Sun starts to make music in clear apricot tones with the changing fall foliage. Colder temperatures transform its green branches into stalks of vibrant yellow, orange and red which glow in an otherwise increasingly dull landscape.
Arctic Sun (a.k.a. Cornus sanguinea Cato) is a compact clone of Blood Twig Dogwood, reaching only 3-4 tall as opposed to 8-10, and this size is useful in smaller gardens. It thrives in average to moist soil in full sun or part shade, is deer resistant, and is hardy in zones 4-7, which means it will take temperatures to minus 30F, but probably wont be happy in mild winter climates. We recommend planting Arctic Sun in a location so that the dazzling winter stems can be viewed from an inside perch, perhaps where you sit with your morning coffee, or where you might pass by as you enter and leave your home. You’ll enjoy the show all winter, and may even be inspired to cut a few branches for decoration.
One thing you should note is that the best color on twig dogwoods is displayed on young wood. Every two or three years you should stool yours plants in early-mid spring. Stooling is a simple pruning technique where you cut back the entire shrub to about 6 above ground. The new growth will provide a more colorful display when late fall and winter arrives.
