Facts
Red raspberry is our common raspberry. It produces canes that last two years, are sterile in their first year, and produce delicious berries in their second year. It is one of the most common species to colonize open sites following logging or fire. Red raspberry is delicious to humans, and many cultivars have been developed from the wild species. Animals including black bear and coyote also consume the juicy fruits. Since the flowers are almost always self-incompatible, this species relies on bees and other pollinators to produce fruit.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields, shores of rivers or lakes, shrublands or thickets, swamps, wetland margins (edges of wetlands)
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

Subspecies idaeus is known from CT, MA, ME, VT. It is non-native and more commonly found in human-disturbed and human-modified habitats. Subspecies strigosus is known from CT, MA, ME, NH, RI, VT. It is native and found in many different habitats, including pristine and human-disturbed.
15b×19. Rubus ×neglectus Peck is a somewhat rare raspberry hybrid known from CT, MA, NH, RI, VT. It is intermediate between the two parental species and can be distinguished by its fruit color and pedicel morphology. The mature fruit is red-purple to purple (vs. red in R. idaeus and purple-black in R. occidentalis). The pedicels are armed with very thin prickles 0.7–1.5 (–2) mm long and have stipitate-glands (those of R. idaeus have thin bristles and are stipitate-glandular whereas those of R. occidentalis have stouter prickles (1.1–) 1.5–2.7 mm long and lack stipitate-glands). Additionally, the stipitate-glands of R. ×neglectus tend to be sparser and/or shorter than those of R. idaeus.
Native to North America?
Yes and no (some introduced)
Sometimes confused with
- Rubus occidentalis:
- fruit purple-black, flower stalks armed with stout prickles and lacking stipitate glands (vs. R. ideaus, with fruit red, flower stalks without stout prickles and with usually stipitate glands).
- Rubus illecebrosus:
- petals large, surpassing the sepals, floricane leaves with 5–9 leaflets, leaflets glabrous on the abaxial surface, and fruit not separating from the receptacle (vs. R. idaeus, with petals smaller, equaled or surpassed by the sepals, floricane leaves with 3 leaflets, leaflets densely tomentose with white-gray to gray hairs on the abaxial surface, and fruit from the receptacle).
