Wildlife Uses:
Sumac fruits are not preferred by most animals and birds but the red fruits do remain on shrubs throughout winter and provide emergency food when more desirable foods are scarce or gone. Birds such as grouse, turkey, bluebirds, and robin rely heavily on the fruits as do many winter songbirds. Rabbits and deer eat bark, fruits and foliage.

Horticulture:

Uses :
Staghorn and Smooth - Large groups on poor soils and waste areas.
Shining - Border, specimen or large group on dry, waste areas.
Fragrant – Groups, foundation planting, rock gardens, cover for banks and steep barren areas.
Poison – All parts too toxic for use near humans.

Light: Full sun.

Soil Moisture: Staghorn, Smooth, Shining – Prefer moist, well-drained soils but can grow on very poor, dry soils. Fragrant – Dry soils. Poison- Wet soils.

Soil pH: Acid to neutral .

Problems: Most sumacs have few serious pests. Verticillium wilt sometimes kills Staghorn Sumac. Sumacs are short-lived but produce root suckers freely which will replace any individuals killed or which die naturally. Poison sumac is too toxic to be considered as an ornamental .
