Pollination Info

Pollination Info for Great Blue Lobelia (Lobelia siphilitica)

Great blue lobelia is a native wildflower found across much of the eastern United States, from Maine to Georgia and in the Midwest. Its flowers are primarily blue, but can also be white or pink.

The plant is pollinated by a variety of insects, including bees, butterflies, and moths. The shape of the flower, with a long, narrow tube and a wide, open throat, is an adaptation for pollination by long-tongued bees like bumblebees. The bees insert their tongues deep into the tube to reach the nectar, brushing against the pollen-producing anthers and stigma.

The flowers are also visited by hummingbirds, which can access the nectar with their long bills. However, they are not efficient pollinators because they usually do not come into contact with the reproductive structures of the flower.

Great blue lobelia blooms from mid-summer to early fall, providing a valuable nectar source for pollinators during this time. Its attractive blue flowers make it a popular plant for gardens and natural areas.
