Lobelia cardinalis (Cardinal Flower)
Lobelia cardinalis, or Cardinal Flower, is one of our most beautiful and popular native wildflowers because it is as striking in the garden border as it is in a woodland setting. This scarlet perennial Lobelia withstands moist to dry soils, and its height will vary accordingly - growing anywhere from less than one foot to at least four feet. Cardinal Flower is a reliable self-sower, and it's always surprising where more pop up each year. I wouldn't dream of dead-heading this one. Sun/part shade (some shade advisable). Zones 3-7. Quarts.
