Thyme-leaf wild buckwheat is a compact, drought-adapted shrublet native to the arid Columbia Basin and thrives in well-drained, rocky or sandy soils with plenty of sun. Water sparingly once established and avoid clay soils or standing moisture, which can cause root rot. It is an excellent low-maintenance choice for xeric gardens, rock gardens, and pollinator plantings in the Pacific Northwest.
