Both native and non-native viburnums ( Viburnum spp.) attract a wide range of pollinators with strong scents that promise either a nectar or pollen reward. Scarab beetles of the genus Cetonia are particularly interesting viburnum pollinators, possessing branched hairs on their bodies that are similar to pollen-collecting hairs found on bees. These hairs ensure a better chance of cross-pollination for self-sterile viburnum species. Viburnums with long corolla tubes and sweet scents are most often pollinated by species belonging to the order Lepidoptera, while viburnums with shorter corolla tubes and muskier odors receive frequent visits from flies and small bees. This relationship corresponds to the size of the insect mouthparts. Most viburnums produce very little nectar despite the wide range of pollinators..  The primary reward, at least for bees, is not nectar but pollen ( Arnold Arboretum ).

Attracts pollinators. Birds and other wildlife consume fruit.
