Coville's sulfur buckwheat is a rare California endemic variety of Eriogonum umbellatum suited to well-drained, rocky soils in open chaparral and montane habitats. It performs best in full sun to part shade and requires little water once established, making it ideal for low-water native and xeriscape gardens. This specialist plant is a wonderful choice for dedicated native plant enthusiasts seeking to support local pollinators.
