A low deciduous shrub that offers attractive flowers in spring and bright fruits and foliage in fall, skunkbush sumac is native to western North America. In mid-spring before the leaves emerge, conspicuous clusters of pale yellow flowers appear at the stem tips. Small berries follow, ripening red in late summer. Resembling poison ivy foliage, the downy three-lobed leaves are mildly glossy and medium to dark green. The leaflets have blunt-toothed edges. Bruised leaves release a malodorous scent. In autumn, the foliage turns fiery colors.
Skunkbush sumac does best in full sun and moderately moist soil, with the brightest autumn color produced under such conditions. In drier soil plants are smaller. Use this extremely hardy shrub as a loose low screen at the edge of a woodland or building, or to clothe a bank or other erosion-prone site. Plants may sucker and form a thicket in some conditions.

|Germination||1. Soak the seeds in a bowl full of 120F (+50C) water. Let the water cool completely. Pour off the cool water. Pour more 120F (+50C) water onto the seeds and soak until the water cools..|
2. Stratify seeds in a plastic bag full of moist sand inside the refrigerator for 90 days. Keep the sand barely moist during the cold stratification period.
3. Sow seed 3/8" deep, tamp the soil, keep moist, mulch the seed bed.
Can be sown outdoors in the fall for spring germination.
Other: if boiling water treatment does not allow seed to imbibe, sulfuric acid treatment is required.
