Description
Toxicodendron radicans is a dioecious perennial that grows in the form of a forb/herb, shrub, subshrub, or vine.[2] Leaves are deciduous, alternate, trifoliate, ovate with dentate margins and can change to a deep orange or red color in the fall. It requires partial to full shade. All parts of this plant are considered poisonous. Oils on the plant contain urushiol, a severe skin irritant, which can cause severe skin redness, itching, swelling and blistering following direct or indirect contact.[3]
Distribution
It can be found from Texas north to South Dakota and Minnesota and in all of the states eastward. It has also been reported in southern Arizona and the Ontario and Quebec provinces of Canada.[2]
Ecology
Habitat
T. radicans is found throughout a wide range of habitats including mesic forests, rock outcrops, open areas, disturbed areas, xeric limestone sites, swamp forests, brackish marshes, bottomlands, maritime forests.[1]
Phenology
Flowering occurs from March to May with fruits appearing in August through October.[1][4] Flowers can contain colors of white, green and/or brown. Fruits are amber in color and 0.25 in (6.4 mm) in diameter.[3]
