Named after the famous redbird of the Midwest, the Cardinal flower (Lobelia cardinalis) are perennial wildflowers with bright red blossoms that cluster around a central stalk. This member of the bellflower family has a long, tubular shape that attracts hummingbirds and butterflies which serve as pollinators as they feed on the nectar.

The cardinal flower grows 3 to 6 feet tall and blooms between late spring and early autumn (May-Oct), when the nighttime temperatures increase. If not planted early enough, first year plants may only produce lance-shaped basal leaves. Both heat and cold tolerant, the cardinal flower is native to the lower 48 United States and eastern Canada and thrives in moist and wet soil, as well as all sun and shade conditions. Herbivores avoid eating the plant due to its having a mild poison; lack of wildlife disturbance helps the plants to live 2 to four years.

Temperature & Moisture
These flowers can handle a wide range of temperatures. However, protection from frost and below freezing helps hibernate successfully. The mulch layer protects the plant and helps it grow healthy the following year. Cardinal flowers loves moisture, so the higher the humidity, the better. For this reason, cardinal flowers are ideal near rain gardens and water bodies.
