Winter may seem like a bleak time for your garden, but if you have red twig dogwood (Cornus sericea), you have a fiery scarlet island in the endless sea of white or brown. The striking shrub, which is native to North America, has winter stems that vary in colour from bright red to dark burgundy. The cultivar ‘Cardinal’ (pictured here) is one of the best for outstanding stem colour. Though red twig dogwood is a brilliant beauty, it’s not high maintenance at all, and it’s not picky—it’ll grow in just about any type of soil.
