Cornus sericea
Redosier Dogwood

This plant has red twigs all year round, but the color is especially prominent in winter. Grows well in a variety of situations, including wet soil. Easy to transplant. Relatively trouble-free. A three-year pruning cycle improves form, vigor, and winter stem color effect. Cutting all stems 6-12" from ground in late winter has similar effect. Best in mass plantings. Excellent for winter color. Leaf blights and twig cankers can be problematic.
