Blackhaw
Viburnum prunifolium
In the United States:
Native
· also called blackhaw viburnum, blackhaw, sweet haw
Blackhaw provides early-season nectar to honeybees during its April to June bloom period, with peak visitation in May, supporting colony buildup without contributing to significant honey flows. Pollen is available but less emphasized for honeybees compared to native small bees. This understory shrub thrives in partial shade and requires no special management for pollinator gardens.
