Eriogonum umbellatum Seeds - Sulfurflower Wild Buckwheat with Yellow Blooms (100 Seeds)

Eriogonum umbellatum, commonly known as sulfurflower or sulfur buckwheat, is a hardy native perennial prized for its cheerful yellow blooms and low-maintenance nature. This versatile wildflower is native to western North America and thrives in challenging conditions, making it an excellent choice for rock gardens, xeriscapes, and pollinator-friendly landscapes. Its compact, mounding habit and long-lasting flowers add texture and color to sunny borders and native plant collections.

In late spring to summer, sulfurflower produces clusters of bright yellow flowers that mature to a rusty orange, providing extended seasonal interest. The blooms are highly attractive to bees, butterflies, and other beneficial insects, while the foliage offers a subtle gray-green backdrop. This resilient plant is drought-tolerant once established and requires minimal care, making it a smart addition to water-wise gardens.

Planting & Care

Sow sulfurflower seeds indoors or directly in the garden after the danger of frost has passed. For best results, cold stratify seeds for 4-6 weeks before sowing to improve germination. Press seeds lightly into the soil surface and keep consistently moist until germination. Once seedlings have developed a few true leaves, thin or transplant them to their final spacing.

Choose a sunny location with well-drained soil. Water regularly during the first growing season to help establish a deep root system, then reduce watering as plants become drought-tolerant. Avoid overwatering and heavy clay soils, as sulfurflower prefers dry, lean conditions. Mulch lightly to suppress weeds, but keep mulch away from the crown to prevent rot.
