Lobelia cardinalis

Cardinal Flower

One of our best-known native wildflowers, Lobelia cardinalis, or Cardinal Flower, adapts well to garden conditions, especially in moist areas beside ponds or water features. It forms an upright mound of glossy dark green leaves, bearing taller spikes of scarlet-red flowers in mid to late summer which bloom successively from the bottom to the top. Attractive to both hummingbirds and butterflies, but not cardinals. One of the few brilliant red perennials and a nice burst of color late in the season.

Additional:
