100 Sulfurflower Buckwheat Seeds Eriogonum umbellatum Pollinator Wildflower

Sulfurflower Buckwheat (Eriogonum umbellatum) is a low-growing western North American wildflower grown for its tidy grey-green foliage and rounded clusters of small, bright yellow blooms that mature toward orange and rust tones in warm weather. A long-blooming, undemanding species, it works well in rock gardens, xeriscapes, and sunny perennial borders where its compact, mat-forming habit softens the front of the planting.
In the garden, Sulfurflower Buckwheat is used as an ornamental groundcover and accent plant on slopes, gravel beds, and dry borders. Its low, dense foliage knits across the soil surface, while the flat flower heads sit just above the leaves on short stems. Growth is slow and steady, forming a rounded mound over time, and the dried flower heads hold their shape into autumn for added seasonal interest.
