David Viburnum (Viburnum davidii) is a shrub species that requires pollination to produce fruit.

Pollination Method

David Viburnum flowers are bisexual and have both male and female reproductive organs. They rely on insect pollination for successful fertilization.

The flowers of David Viburnum attract a variety of pollinators, including bees, butterflies, and other insects, with their nectar and fragrance.

Pollination Season

The pollination season for David Viburnum occurs in the late spring or early summer when the shrub is in full bloom. This period usually lasts for several weeks.

Pollination Requirements

David Viburnum requires cross-pollination to produce fruit. This means that pollen from one flower must be transferred to another flower on a different plant to enable fertilization and fruit development.

The availability of appropriate pollinators is crucial for successful pollination. Gardeners can encourage pollinators to visit their gardens by providing a diverse range of flowering plants and avoiding the use of pesticides.

Fruit Production

Fruit development in David Viburnum relies on successful pollination. If pollination does not occur, the flowers will wither and die without producing fruit.

Once pollination is successful, the flowers will develop into red or blue-black berries that attract birds and other wildlife. These berries can take several months to mature.
