Rubus hartmanii

Rubus hartmanii is a European microspecies within the Rubus fruticosus aggregate (bramble or blackberry group), a taxonomically complex assemblage of apomictic shrubs in the Rosaceae. It forms a scrambling, thorny perennial shrub with biennial canes (primocanes vegetative, floricanes flowering) bearing recurved or straight prickles. Leaves are palmately compound with 3 to 5 serrate leaflets, dark green above and paler, often tomentose, beneath. Flowers are white to pale pink, five-petalled, borne in terminal panicles in summer. Fruits are aggregate drupelets ripening from red to glossy black, edible and sweet. Distributed across temperate Europe in hedgerows, woodland margins, and disturbed ground. As one of hundreds of agamospecies within R. fruticosus s.l., its morphology and chemistry closely parallel the broader complex.
