Lobelia Siphilitica is simply gorgeous! Exciting cobalt blue flowers emerge from lush, green plants in late summer. A wetland native, this blue lobelia will do very well as a bog plant, in borders, at the edge of a pond or simply in your flower bed. Unusual, late season color when other plants are winding down. Grows 1 - 3 feet tall in filtered shade and prefers wet, loamy soil. Small, blue "bells" form the lovely flower spikes. Attracts hummingbirds and butterflies.
