Grassland agoseris is a native perennial wildflower from western North America, well suited to meadow gardens and naturalized landscapes. It prefers well-drained soils in full sun to part shade and is relatively undemanding once established. A great choice for native plant enthusiasts seeking to attract pollinators to open garden areas.
