Lobelia cardinalis - cardinal flower
Lobelias are not true perennials because the flowering stem and roots die after setting seed. It is, however, a beautiful wildflower that competes well with sedges and grasses and other wildflowers.
Lobelia cardinalis or cardinal flower grows in moist locations and is a clump-forming perennial with large cardinal red flowers in late summer. Its flowers are very attractive to butterflies and hummingbirds, but not cardinals. White and rose-colored forms are also known.
"If you are fond of red and have a moist open spot, you owe it to yourself to grow this plant". Growing and Propagating Wildflowers, William Cullina
