Soft, cool colors dominate the western prairies in the passing minutes between sunset and darkness. To experience such a time of day in such a place is like nothing else, and serves as the inspiration for this designer mix. Soft pinks, purples, blues and whites define a color palette of calmness and tranquility, made up of primarily native species to our western plains. Among these are the hardy Echinacea, Liatris and Baptista, all well suited to USDA Zones 3-8. A must for large expanses of plantings and transitional zones involving stone walls.
