Family, Lobelia. Color, light blue. Calyx-tube, short, 5-cleft. Corolla, bell - shape, longer than the calyx-tube, but split down on the upper side, slightly 2-lipped; upper lip 2, lower 3-lobed, 1 inch long, showy. Leaves, thin, numerous, ovate or lance-shape, irregularly serrate. Flowers, pedicelled, in a dense raceme, with leafy bracts. July to October.
The blue of this lobelia is rather pale, fading sometimes to nearly white. It is a hairy, tall-stemmed plant, 3 feet high, with a long, leafy panicle of showy flowers. A near relative of the cardinal-flower. As the pistil matures after the anthers have discharged their pollen, this is a flower specially prepared for cross-pollination.
In low, damp grounds, Maine to Minnesota, south to Georgia, Louisiana, and Kansas. (See illustration, p. 354.)
