Key Facts
- Deciduous small tree or large multi-stemmed shrub in the cashew family
- Distinct fuzzy or velvety young stems that resemble stag antlers
- Native to eastern North America and naturalizes in disturbed sites
- Forms colonies by root suckers and can spread into thickets
- Showy dense clusters of red fruit persist into winter and feed birds
- Tolerant of poor, dry, and rocky soils and urban conditions
- Best fruiting and compact form occur in full sun
- Used historically for a lemony spice made from the dried fruit
Staghorn Sumac is a deciduous small tree or multi-stemmed shrub prized for fuzzy young stems and dense red fruit clusters that persist into winter. It tolerates poor, dry soils and naturalizes by root suckers so use it where spreading thickets are acceptable or can be managed.
Identification
Look for velvety young stems that resemble stag antlers and pinnate leaves that turn color in autumn. Mature plants typically reach 15 to 25 feet tall and a similar spread, and they produce dense upright clusters of red fruit after late spring to early summer flowering. Birds feed on the persistent fruit through winter.
Best uses and where to grow
Use Staghorn Sumac for massing on slopes, erosion control, wildlife cover and naturalized edges where a thicket habit is acceptable. It tolerates city planting and poor rocky or clay soils and performs best in full sun for compact form and best fruit. Avoid poorly drained, waterlogged sites where it will decline.
Planting and spacing
Space plants according to their mature spread, typically 15 to 25 feet apart when used as specimen trees or screens, and allow extra room if you want a single-trunk specimen rather than a clump. Choose a sunny to partly shaded spot with well drained soil for best fruiting and a more compact habit.
Watering and soil
Staghorn Sumac establishes on dry, rocky and poor soils and is drought tolerant once settled. Water regularly during the first one to two growing seasons so roots develop, then reduce irrigation; overwatering or poor drainage leads to root decline. It tolerates a wide pH range but needs free-draining soil to stay healthy.
After-flowering care and wildlife value
After flowering the dense red fruit clusters persist into winter and provide food for birds. Leaving some fruit stalks benefits wildlife while selective pruning of dead wood keeps form tidy. The plant makes a strong visual statement in fall and retains ornamental interest through winter where fruit is left intact.
Controlling spread and maintenance
Staghorn Sumac spreads by root suckers and can form thickets if unmanaged. Control spread by removing new suckers promptly at the root crown or installing a root barrier to limit lateral roots. Regular removal of unwanted shoots maintains a single specimen; expect more vigorous suckering in warmer parts of its USDA 3 to 8 hardiness range.
Propagation
Propagate by seed, root suckers, layering or cuttings. Seed generally requires cold stratification before sowing to break dormancy. The fastest way to expand an existing stand is by transplanting root suckers or layering stems taken from established plants.
Frequently asked questions
- How fast does Staghorn Sumac grow?
- Growth is generally moderate to fast and plants commonly reach 15 to 25 feet tall. Spread increases over time through root suckers and can form colonies if left unchecked.
- Is Staghorn Sumac invasive?
- It readily naturalizes and forms thickets by suckering. Check local regulations and manage suckers if planting near lawns, garden beds or natural areas where spread is unwanted.
- Is it poisonous to people or pets?
- Staghorn Sumac is distinct from poison sumac and is generally regarded as non toxic to cats, dogs and horses. Sensitive individuals may still get contact dermatitis from sap or related species so avoid skin contact if prone to reactions.
- Can I use the fruit?
- The dried fruit has been used historically as a lemony spice. Harvest and prepare cautiously and consult local foraging guidance before using wild plant material.
- How should I prune it?
- Remove unwanted suckers at the root and cut back dead or crossing branches to maintain form. Timing and extent of pruning vary by climate and landscape goal.
