Euphorbia polychroma, commonoly called cushion spurge, is a mounding, clump-forming perennial which typically grows in a dome (or cushion) shape to 12-18" tall and as wide on erect, sturdy stems bearing oblong, downy, medium green leaves (to 2" long). Cymes of inconspicuous greenish flowers (lacking both sepals and petals) bloom at the stem ends in spring. Although the flower cymes are not showy, they are subtended by long-lasting, bright sulphur-yellow bracts which are exceptionally showy. Stems exude a toxic, milky sap when cut. Leaves turn red in fall. Synonymous with Euphorbia epithymoides.Genus name honors Greek physician Euphorbus (52 B.C - 23 A.D.).Specific epithet means of many colors.'Bonfire' was bred by Mary Ann Faria of Limerock Plant Farm from an two unnamed Euphorbia polychrome plants.
