100 Sulfurflower Seeds Eriogonum umbellatum Heirloom Native Wildflower Rock Garden

Sulfurflower (Eriogonum umbellatum) is a native wildflower known for its bright sulfur-yellow blooms and low-growing habit. It is a long-lived perennial that adds long-lasting color and texture to sunny, well-drained sites. Its nectar-rich flower clusters appear through summer and draw a wide range of pollinators. The gray-green foliage forms tidy, mounding clumps that fit well in rock gardens, borders, and native plantings.

This species is valued for its durability and drought tolerance once established. Use it in rock gardens, pollinator plantings, xeriscapes, or as a low-maintenance groundcover in tough, dry areas. Plants generally bloom from early to mid summer, with dried flower heads holding interest into fall. For best results, sow on the surface, as light aids germination, and keep the medium evenly moist until germination occurs.
