As you can see, this is an attractive plant. It is extremely dangerous, though, and no one in their right mind would want it in their garden or would want to propagate it. It does have a place in nature.

These pictures were taken in a state park within easy reach along the roadside . Everyone should learn to recognize this dangerous plant.

Poison Sumac grows in wet soil and shaded hardwood forests along the Eastern Coastal Plains and the Great Lakes. The foliage is green in summer, but turns red in the fall. The bark is gray mottled with black spots where the sap comes to the surface. If this sticky substance comes in contact with your skin, it can create a painful rash similar to that created by poison ivy, only more intense. Gray white fruit, drupes, appear in late summer. While other mammals feed on the leaves and berries, they are considered toxic to man.
