100 Seeds Sulfurflower Buckwheat Eriogonum umbellatum Drought Tolerant Perennial Groundcover Native Wildflower
Sulfurflower Buckwheat is a low-growing perennial native to western North America, valued for its neat mat-forming habit and long-lasting display of bright sulfur-yellow flower clusters. Blooming through late spring and summer, the rounded umbels sit just above a tidy cushion of small green leaves, making it an attractive, low-water choice for rock gardens, borders, pollinator plantings, and dry slope coverage.
Easy to grow and tolerant of poor, well-drained soils, Sulfurflower Buckwheat works well as a foreground plant, edging, or container subject and pairs nicely with other drought-adapted perennials. Its flat-topped flower heads provide a landing platform for small insects, while the dried seed heads and russet winter foliage extend seasonal interest. Plant in full sun for the tightest, most floriferous habit.
