Grey Twig Dogwood (Cornus racemosa) is pollinated by a variety of insects including bees, flies, and butterflies. The flowers of the Grey Twig Dogwood are small and white, and they bloom in the late spring. They are arranged in a cluster at the end of the branches. The flowers produce nectar that attracts pollinators.

Once the pollinator lands on the flower, it will crawl around searching for nectar. As it moves around, it brushes against the anthers of the flower, transferring pollen to its body. When the pollinator moves on to the next flower, some of the pollen from the first flower will be deposited on the next flower's stigma, resulting in pollination.

Grey Twig Dogwood is a self-compatible species, which means that it can produce seeds without the need for cross-pollination. However, cross-pollination from another individual can increase the genetic diversity of the offspring, leading to healthier and more resilient populations.
