This variety of round-headed buckwheat is a low-maintenance native perennial native to the arid slopes of the western United States, thriving in rocky, well-drained soils with minimal supplemental water. Provide full sun to part shade and water sparingly, especially once established, as this plant is well adapted to dry conditions. It is an excellent choice for native plantings, rock gardens, or pollinator-friendly landscapes.
