The Great Blue Lobelia is a native North American perennial that is known for its striking blue flowers. This plant is primarily pollinated by bees, especially bumblebees and solitary bees. The tubular shape of the flowers makes it easier for bees to access the nectar and pollen within.

The reproductive organs of the Great Blue Lobelia are well-positioned within the flower to facilitate pollination. The anthers, which contain the pollen, are located near the entrance to the flower, making it easy for visiting pollinators to brush against them and pick up pollen. The stigma, which receives the pollen for fertilization, is positioned in a way that ensures contact with pollen as the pollinator feeds on nectar.
