Quick Overview:

Great lobelia is a native perennial which typically grows in moist to wet locations along streams, sloughs, springs, swamps, meadows and in low wooded areas. A clump-forming perennial which features light to dark blue, tubular, 2-lipped flowers with the three lobes of the lower lip appearing more prominent than the two lobes of the upper lip. Flowers arise from the upper leaf axils forming a dense terminal raceme atop stiff, unbranched, leafy stalks typically rising 2-3′ tall. Finely-toothed, lance-shaped, light green leaves (to 5" long). Late summer bloom period. Species name of siphilitica arose from a prior medicinal use of the plant in the treatment of venereal disease. Also sometimes commonly called blue cardinal flower.
