Pennsylvania Blackberry
Rubus pensilvanicus
Honeybees heavily forage on Pennsylvania blackberry for its abundant nectar and pollen, contributing to summer honey flows in its native range. Peak bloom occurs in May to June, providing a reliable early-summer resource after spring flows. The thorny canes can spread aggressively in disturbed areas, requiring management to prevent overgrowth near apiaries.
