Prostrate Sulphur Flower
Eriogonum umbellatum var. humistratum var. humistratum
This low-growing California-endemic buckwheat variety prefers partially shaded exposures with excellent drainage and minimal irrigation after establishment. It is ideal for California native gardens, dry slopes, or rock gardens where it can spread slowly without competition. Avoid summer overwatering, which is the most common cause of failure.
