Great blue lobelia (Lobelia siphilitica) is a common occuring plant in low lying areas, along streams, ponds, springs and meadows.
Great blue lobelia grows in full sun to part shade (although we have tested in areas that are nearly full shade and the plant still blooms, although slightly later in the season, which is helpful to those late season nectar chasers). This plant attracts hummingbirds although not as readily as it's counterpart Red cardinal flower.
The seeds are dispersed by wind in the fall and do very well in areas with rich moist soils. It is a clump forming perennial that grows 2-3 feet in height. It grows in hardiness zones 3-9. Blooms typically occur between July through October in it's natural growing zones.
Great blue lobelia is native to the following areas of North America:
