Fragrant Sumac
Rhus aromatica
  
About Fragrant Sumac (Rhus aromatica) 20 Nurseries Carry This Plant Rhus trilobata is a shrub in the Anacardiaceae (Cashew) family with the common name Fragrant Sumac and several others. It was formerly classified as Rhus trilobata and some sources still refer to it that way. It is native to western North America. In California it occurs in many parts of the state including the northern Coast Ranges, Sierra foothills and southern coastal mountains. It can be found from deserts to mountain peaks up to about 7,000 feet in elevation. The pale yellow flowers are followed by a red, fleshy drupe that has a sticky coating, similar to Lemonade Berry. This species closely resembles other members of the genus that have leaves with three "leaflets" ("trifoliate" leaves), including Poison-oak. People with sensitivity to Poison-oak should use caution around Fragrant Sumac. The shape of the leaflets and the habit of the shrub make this species, like some other Rhus, resemble small-leafed oaks (Quercus). The plant is deciduous and exhibits good fall color.
