Pollinators:

Buddleia 'Black Knight' is known for attracting a wide range of pollinators, including butterflies, bees, and hummingbirds. The fragrant flowers of this shrub produce an abundance of nectar, which is irresistible to these pollinators.

Pollination Process:

When pollinators visit the flowers of Buddleia 'Black Knight' to feed on nectar, they inadvertently transfer pollen from one flower to another, leading to successful pollination. This process is essential for the production of seeds and the continued growth of the plant.
