Sumacs (Rhus spp., family Anacardiaceae) are native to North America and Africa, prized for brilliant fall foliage and wildlife value. About 250 species exist—most are benign, but a few cause severe allergic reactions. Learning to distinguish them is essential.
| Species | Key Features | Habitat | Berries |
|---|---|---|---|
| Smooth Sumac (Rhus glabra) | 10 ft; alternate serrated leaves turn crimson; green spring flowers | Dry, open areas | Bright red, upright clusters |
| Staghorn Sumac (Rhus typhina) | 18–34 ft; hairy/velvety stems (like antlers); jagged leaves; conical red drupes | Adaptable; prefers dry soil | Red, upright |
| Poison Sumac (Rhus vernix) | Wetlands/swamps; smooth pinnate leaves; NO hair on stems; white/gray berries hang down | Swamps, bogs | White, pendulous |
| Poison Ivy (Toxicodendron radicans) | Shrub/vine/groundcover; 3 leaflets; reddish fuzzy vines; pale yellow flowers; white drupes | All soil types | White |
| Fragrant Sumac (Rhus aromatica) | Cool mountains; citrus-scented leaves; NO petiole (vs. poison ivy); yellow flowers | Rocky slopes | Red, upright |
Critical ID rule: Non-poisonous sumacs have red, upright berry clusters. Poisonous species have white, hanging berries and smooth (non-hairy) stems.
Poison sumac and poison ivy cause severe contact dermatitis. Never burn them—smoke carries urushiol oil. If unsure, don't touch. Consult an expert for removal.
