Growing to a height of 4 ft. to 6 ft. this dense sub-shrub can form clumps up to 3 ft. wide. Beautiful half inch sky blue flowers each having a white stripe down its throat. The blooms are arranged along the end of the airy stems. Wonderful for meadows and borders, also lives up to its other name of Bog Sage growing quite well on the edge of ponds. Enjoys a full sun location. Hardy to Z 6
