Simpson's buckwheat is a resilient native perennial from the western United States, performing best in rocky or sandy, well-drained soils with partial shade to full sun. Water consistently during the first growing season to help establish roots, then taper off as the plant adapts. It rewards gardeners with delicate flowers that attract bees and butterflies throughout the summer.
