About
Eriogonum umbellatum, the sulphur buckwheat, is one of the most ornamental and variable of all the buckwheats, forming a sprawling to compact perennial or subshrub with grey-woolly leaves and flat-topped umbels of bright-yellow flowers in summer that age to orange-red. A superb and drought-tolerant plant for a sunny, well-drained rock garden or gravel bed.
