Description:
Robust, compact, rounded, hardy plant for northern gardens with very refined, 3-lobed cut leaves, which produces impressive, large, 8 in. wide lavender flowers from summer to fall. Useful in mass, as a hedge, along the edge of a pond, or in water up to 6 in. deep. Very late to break dormancy and you may think it did not survive winter, but once it emerges from dormancy, the plant will become a showy accent. Mature height of 3 ft. with a similar spread. Plant in moist, well drained soil in full sun.
