In these environments E. virginiana are pollinated by Prenolepis imparis, the winter ant. This insect pollination is required for pollination in the chasmogamous flowers. E. virginiana relies upon ant pollination to produce cross pollinated seeds along with self-fertilized seed.
In specific environments, E. virginiana is fertilized by Prenolepis imparis, the winter ant. Insect pollination plays a crucial role in the reproduction of chasmogamous flowers in this plant species. E. virginiana relies on insect pollination to produce seeds that are a result of both cross-pollination and self-fertilization.
