P. vacciniifolium, 6 to to in., is a pretty prostrate subshrubby species, with handsome rose-pink flowers, suitable for rockwork, and prefers boggy soil; P. affine (Brunonis), I ft., deep rose, is a showy border plant, flowering in the late summer; P. cuspidatum, 8 to To ft., is a grand object for planting where a screen is desired, as it suckers abundantly, and its tall spotted stems and handsome cordate leaves have quite a noble appearance.
