Shrub Cornus alba [Tatarian Dogwood] 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.

Can appear a bit coarse in the landscape.
Shrub/Tree Cornus mas [Cornelian Cherry Dogwood] Large multi-stemmed shrub or small tree of oval rounded outline, usually branching to the ground. Small yellow flowers are beautiful when borne in mass in the spring. No serious disease problems. Sometimes it suckers abundantly, and these suckers should be removed to control spread; this is especially important if maintaining this plant in tree form.
Shrub/Tree Cornus officinalis [Japanese Cornel Dogwood] The Japanese Cornel Dogwood is a large multi-stemmed shrub or small tree of oval rounded outline, usually branching to the ground. No serious disease problems, although it sometimes suckers abundantly. These suckers should be removed to control spread; this is especially important if maintaining this plant in tree form.
