Eriogonum umbellatum var. umbellatum

The nominate variety of sulfur buckwheat is a classic western native ground-hugging perennial valued for its bright yellow flower clusters and silvery foliage. Plant it in well-drained, sandy or rocky soil in partial shade to full sun; it handles dry summers with ease once established. This variety is a great choice for xeriscape, native, and rock garden designs across the Mountain West.
