This is apparently our native red raspberry. The most interesting aspects of this plant are its relatively small stature and upright habit, although some forms are more spreading or decumbent. The taxonomy of this species seems to be in flux. Some authorities consider it to be a unique species from the Eurasian var. idaeus and refer to it as R. strigosus Michx.

Eurasian plants are said to lack stipitate-glandular hairs and occur in more upland habitats. These are commonly cultivated and occasionally escape. The images below were taken in a forest in central NY and may or may not represent our native red raspberry as the glandular hairs are present but not as distinct.
