In mid-spring, the black chokeberry begins to grow clusters of small, white flowers with pink anthers. The flowers are perfect with 5 petals, allowing them to self-pollinate. Additionally, they also use organisms, such as bees and butterflies, to aid in their pollination. However, these flowers were not observed when surveying the plant. In the late summer, the black chokeberry begins to form small dark purple-to-black fruit containing seeds. These fruit are useful for continued reproduction as birds, rodents, small mammals, and other animals are able to consume the fruit and pass the seeds through their excrement.
