Description
Rubus cuneifolius is a dioecious perennial subshrub.[2]
Distribution
R. cuneifolius is found primarily on the coastal plains from Connecticut and New York south to Florida, Alabama, Mississippi and Louisiana.[1][2]
Ecology
Habitat
R. cuneifolius commonly inhabits woodlands, forests, and disturbed areas.[1] This includes early successional areas.[3] It uses a medium amount of water, requires partial shade, and has a medium tolerance to calcium carbonate.[4] A study in the Great Dismal Swamp, Virginia, found R. cuneiolius was present in uncut-burned areas with a mean biomass of 1.16 g m-2 yr-1.[5]
Phenology
Flowering occurs between March and June, peaking in April,[1][6] with fruiting occurring from May through July.[7] R. cuneifolius produces a white conspicuous flower.[4] The timing of flowering has been shown to be sensitive to ozone levels where elevated levels cause earlier flowering but produce fewer large ripe fruits.[3]
Seed bank and germination
Seeds of R. cuneifolius were commonly observed in Georgia seed banks of longleaf pine - wiregrass - bracken fern forests maintained by annual spring burns since 1961.[8]
Pollination
R. cuneifolius is recognized to attract a large number of native bees for pollination.[4]
Use by animals
Berries produced by R. cuneifolius are highly palatable by browsing animals, composing 10-25% of the diet for many species of terrestrial birds, large mammals and small mammals. It is also an occasional source of cover for small mammals and terrestrial birds.[2] Because R. cuneifolius fruits in the late summer, it is likely an important source of energy for fall migrating bird species.[7] Besides attracting pollinators, R. cuneifolius is known for providing nesting materials/structure for native bees.[4]
Diseases and parasites
R. cuneifolius hosts several species of thripes (Frankliniella spp.) which are tiny insects (1 mm or less) that feed on new plant growth producing cosmetic damage and sometimes transmitting diseases to the plant.[9]
