Pollination Information for Annabelle Hydrangea

Annabelle hydrangeas (Hydrangea arborescens 'Annabelle') are deciduous shrubs that produce large, white, ball-shaped flowers in early summer. These flowers are important sources of nectar and pollen for bees, butterflies, and other pollinators. Here are some details about the pollination of Annabelle hydrangeas:

• Annabelle hydrangeas are mainly pollinated by bees, including bumblebees, honeybees, and solitary bees.
• The flowers of Annabelle hydrangea are primarily visited by bees in search of nectar. However, while collecting nectar, the bees also pick up and transfer pollen from the flower's anthers to its stigma, resulting in pollination.
• Annabelle hydrangeas do not require a specific pollinator for successful pollination. As long as bees are present, pollination will occur.
• Insects such as butterflies and moths may also visit Annabelle hydrangeas for nectar, but they are less effective at pollination than bees.
• Annabelle hydrangeas are self-compatible, which means that they are capable of fertilizing their own flowers. However, cross-pollination (transfer of pollen from one plant to another) may result in greater fruit and seed production.
• To attract bees and other pollinators to your Annabelle hydrangeas, plant them in full sun or partial shade in well-drained soil with good organic content. Avoid using pesticides that may harm pollinators.
