This is a small, slender species, growing only from six to twenty inches high, in wet meadows and on wet banks, where it increases from perennial offshoots and blossoms from July to September. The smooth, light green stalk is erect, leafy and branching. The leaf is very narrow, blunt-pointed, and nearly toothless. The upper ones clasp the stalk. The small, light blue flowers are arranged in sparse, loose, terminal spikes. The three lobes of the lower lip are spotted with white at the throat. The upper lip has two upright parts, and the stamens peek from between them. This Lobelia is found in grassy colonies from Nova Scotia to New Jersey, and westward to Ohio, Michigan and Manitoba.
