Blackberry bramble
Rubus fruticosus
In the United States:
Invasive
Listed as invasive. Check local regulations — several jurisdictions restrict planting.
Honeybees visit blackberry brambles extensively for their plentiful nectar and pollen, contributing to a major honey flow in temperate regions during the bloom period. Peak flowering occurs in early to mid-summer, offering a consistent forage resource when other sources may dwindle. The vigorous, thorny growth habit necessitates regular pruning and containment to manage spread and encourage healthy flowering.
