Zimmerman Cherry Laurel (Prunus laurocerasus 'Zimmerman') is a stunning ornamental shrub that produces white, fragrant flowers in the spring and bright red berries in the fall. The plant provides an excellent source of nectar for pollinators such as bees, butterflies, and hummingbirds.

The Zimmerman Cherry Laurel is primarily pollinated by bees, especially the honeybee (Apis mellifera). These bees are attracted to the plant's sweet-smelling flowers, which provide them with a rich source of nectar. As bees visit the flowers, they inadvertently transfer pollen between the stamens (male reproductive parts) and the pistils (female reproductive parts) of the flowers.

While bees are the primary pollinators of the Zimmerman Cherry Laurel, other insects may also play a role in pollination. Butterflies, for example, may visit the flowers for nectar and inadvertently transfer pollen as they move from flower to flower. Hummingbirds, which are attracted to the bright red berries in the fall, may also visit the flowers and inadvertently transfer pollen as they feed.

Overall, the Zimmerman Cherry Laurel is an excellent choice for gardeners looking to attract pollinators to their yard. The plant's fragrant flowers and bright red berries provide a valuable source of nectar and food for bees, butterflies, and hummingbirds, helping to support local ecosystems and promote biodiversity.
