Winged Sumac (Rhus copallinum) - How to Grow & Care Guide

Plant Snapshot

Common Name: Winged Sumac
Latin Name: Rhus copallinum
Alternate Names: Shining sumac
Hardiness Zones: USDA zones 4–9.
Typical Height: 6–15 ft (1.8–4.6 m).
Typical Spread: 6–12 ft (1.8–3.7 m).
Bloom Period: Late spring to early summer.
Soil Preferences: Well drained soils, dry to medium moisture. Tolerates poor, rocky, sandy soils. Prolonged wetness is problematic.
Light Preferences: Full sun to light shade. Best fruit set and fall color in full sun.
Toxicity: Fruits have been used as a tart flavor and are edible after processing. Sap can cause contact dermatitis in sensitive people and handling should be done with caution.
Propagation: Seed with cold stratification, root sucker division, and stem cuttings. Sprouts freely from roots.

Spreads by root suckers and can form colonies.
Attracts birds with its dense fruit clusters.

Winged Sumac is a deciduous multi stemmed shrub or small tree native to eastern North America. It is prized for showy clusters of red fruit in fall that persist into winter and for tolerating dry rocky and poor soils once established.

Identification and key traits

Leaves have paired winged rachises that give the plant its common name. Small yellow green flowers appear in late spring to early summer and lead to dense clusters of red drupes in fall that attract birds. Typical height ranges from 6 to 15 feet and spread commonly reaches 6 to 12 feet where suckering occurs.

Where to grow and best uses

Suitable for native plantings massed hedgerows erosion control and wildlife edges in USDA zones 4 to 9. It performs best in full sun to part shade and provides reliable fall color and winter fruit. Avoid planting in poorly drained wet sites because prolonged wetness causes decline.

Planting and spacing

Space plants according to the expected spread which is commonly 6 to 12 feet to allow room for thicket formation. Plant with the root crown at soil level and firm soil around the roots. Establishment is easier in well drained soils and plants on richer sites may reach the upper size range more quickly.

Watering and soil

Once established Winged Sumac tolerates dry soils including rocky and sandy sites but prefers well drained conditions. Provide regular water until roots are established then reduce frequency. Prolonged wet soil leads to decline and reduced sucker production which limits naturalizing habits.

After flowering and winter interest

Flowers appear in May and June with fruit developing later and persisting into winter providing visual interest and bird food. Remove dead wood and shape in late winter before new growth starts. Prune only as needed to maintain form and to remove unwanted suckers.

Controlling spread and maintenance

Winged Sumac spreads by root suckers and can form colonies if left unchecked. Control unwanted spread by cutting new shoots at the base or digging and removing suckering roots. Root barriers or regular removal of basal shoots work well where a single specimen is preferred.

Propagation

Propagate by seed by using cold stratification and by dividing root suckers or taking cuttings. Seeds and vegetative shoots establish readily and suckering makes colony formation an easy propagation method. Confirm recommended stratification times and cutting techniques from propagation guides for best results.

Frequently asked questions

How fast does Winged Sumac grow?: Growth rate varies with site fertility and competition. Plants on good sites often reach mature size within several years while poorer sites slow vertical growth but encourage suckering.
Is Winged Sumac invasive?: It is not classed as a widespread invasive but it spreads by root suckers and can form dense colonies. Manage by removing unwanted shoots or using a root barrier where spread is a concern.
Are the berries edible?: Berries have been used historically as a tarting agent and for beverages and can be eaten after processing. Verify preparation methods and avoid consuming wild fruits unless you have reliable guidance.
Does Winged Sumac cause skin irritation?: Sap can cause contact dermatitis in sensitive individuals because it is in the same family as other dermatitis producing plants. Handle with care and wear gloves if you are sensitive.
How should I prune Winged Sumac?: Prune to remove dead wood and to control form in late winter before new growth. Cut basal suckers at their source if you want to limit colony spread.
