Round-headed buckwheat is a tough, drought-adaptable native shrub best suited to well-drained rocky or sandy soils in full sun to part shade. Water occasionally while establishing, then reduce frequency as the plant matures. It thrives with minimal intervention and is an excellent choice for native or xeriscape gardens in the Pacific Northwest.
