Pollination Information for White Flowering Dogwood (Cornus florida)

White Flowering Dogwood (Cornus florida) is a deciduous tree that belongs to the family Cornaceae and is commonly found in the eastern parts of the United States. The tree is known for its beautiful white flowers, which bloom in early spring, and its attractive red berries.

Pollination of White Flowering Dogwood is carried out by insects, particularly bees and butterflies. The flowers produce nectar and pollen, which attract these insects to the plant. The bees collect the nectar and pollen while the butterflies feed on the nectar alone.

White Flowering Dogwood is mainly a cross-pollinated plant, which means that it requires pollen from other trees to reproduce. The flowers are hermaphroditic, meaning that they contain both male (stamens) and female (pistil) reproductive structures. The male reproductive structures produce pollen grains while the female reproductive structures contain the ovules, which when fertilized by the pollen grains develop into seeds.

As the bees and butterflies visit the flowers in search of nectar and pollen, they also transfer pollen from the male reproductive structures of one flower to the female reproductive structures of another flower. This process of transferring pollen from one flower to another is known as cross-pollination, and it is essential for the production of seeds.

Overall, White Flowering Dogwood is an important plant species that supports the pollination ecosystem, providing food and habitat for bees and butterflies, and contributing to the production of seeds for the next generation of trees.
