Redbird flower is also known as cardinal flower, a showy perennial native to North America. It is sometimes called Indian Pink due to its vibrant red color. Other synonyms for redbird flower include lobelia cardinalis, scarlet lobelia, and great lobelia. It is a favorite plant of hummingbirds and other pollinators. The leaves of the plant are toothed and lance-shaped, and the flowers bloom from mid-summer to early fall. The plant prefers moist soil and can grow up to six feet tall in optimal conditions. Redbird flower is often used in wildflower gardens and naturalized areas for its bright color and impressive height.
