Cornus are the choice for winter colour – and there are varieties of cornus with red, orange, green and purple stems. I found these at the Clockhouse Nursery: Cornus alba ‘Siberica’ and Cornus stolonifera ‘Flaviramea’ . Where to put them in the garden though? Bare stems don’t work very well against a wall or a fence. They show best against evergreens or against the sky, and the best place of all is a position where they can be reflected in water.
