Cultivation
Eriogonum crocatum has entered limited cultivation in native plant gardens and xeriscaping. It likes sun and is drought tolerant. It rarely exceeds 0.5 m in height and 1 m in width, so it makes an excellent accent plant. It thrives in clay soils and survives some other soils. It is reportedly difficult to cultivate outside of the southern California area. It can tolerate light freezes.
