Evergreen, spiny-leaved tree of moist woodland understoreys; its small white flowers in May–June give moderate nectar and pollen.
Holly is a small tree with glossy, dark green, spiny leaves, common in the understorey of Black Sea forests under beech and spruce. It is dioecious; male plants give pollen and nectar, female plants nectar. Its small, white, faintly scented flowers are regularly visited by bees.
It flowers in May–June for about two to three weeks. Plants growing in shade flower less; sunlit trees at forest edges are more productive for bees.
No separate honey is obtained; its nectar blends into forest blossom honey. The pollen gives extra protein to colonies developing in late spring.
The red berries are poisonous to humans and pets, but no problem is known from the nectar or honey. Because branches are gathered for Christmas decoration, in some regions it is regarded as a species in need of protection.
