100 Seeds Eriogonum umbellatum Sulfurflower Native Perennial Drought Tolerant Wildflower

Eriogonum umbellatum, commonly known as sulfurflower or sulphur buckwheat, is a low-growing native perennial valued for its neat mat of evergreen foliage and clusters of bright sulfur-yellow blooms. In late spring and summer, the flowers rise above the leaves and dry to a warm rust-orange tone that holds well into fall, giving the plant multi-season interest. It is a long-lived, fuss-free species that suits rock gardens, borders, pollinator plantings, and water-wise landscapes.
This plant works especially well in drought-tolerant beds, gravel gardens, and native wildflower meadows, where its low cushion form and long bloom period add texture and color. It pairs nicely with other sun-loving perennials and ornamental grasses, and its dried flower heads can be left standing for winter structure. Grow it in a sunny, sharply drained spot and allow the soil to dry between waterings for best performance.
