The lower portion of the stems showcases lance-shaped leaves. Usually, the flowers are a vibrant shade of red and five-lobed. The red lobelia is from the bellflower family. Although the red lobelia is relatively common to be found, they have become sparse in some locations due to overpacking. Most insects see that the long tubular flowers are a bit difficult to navigate, and so the cardinal flower depends on being pollinated by hummingbirds who feed on the nectar.
