Pollination Information for Vanilla Strawberry Hydrangea

The Vanilla Strawberry Hydrangea (Hydrangea paniculata 'Renhy') is a partially self-fertile plant, which means that it can produce some seeds if pollination occurs within the same plant. However, cross-pollination with another compatible hydrangea plant will increase seed production and overall plant health.

Insects, particularly bees, are the primary pollinators of the Vanilla Strawberry Hydrangea. These insects are attracted to the shrub's white or pinkish-white flowers, which offer nectar and pollen as rewards for the pollination services they provide.

When selecting a site for planting the Vanilla Strawberry Hydrangea, it is important to ensure that the shrub has access to abundant sunlight and a well-draining soil. These conditions will help to attract and support pollinators, leading to increased seed production and a healthier plant overall.
