This native perennial produces striking blue, tubular flowers in mid to late summer. The flowers arise on tall stalks above clump-forming plants. Best grown in rich, organic soils that remain moderately damp to wet, in full sun or part shade. Grow in part shade where summers are hot. Under optimum conditions, Lobelia will form attractive colonies.
