Great Blue Lobelia
Great Blue Lobelia forms a flower spike covered in deep blue flowers from late summer to early fall. The erect, 2-3 ft., stems produce lavender-blue, tubular flowers crowded together on the upper stem. Showy, bright blue flowers are in the axils of leafy bracts and form an elongated cluster on a leafy stem. This blue counterpart of the Cardinal Flower (Lobelia cardinalis) is a most desirable plant for woodland gardens especially since it blooms bright blue in late summer.
