ISI 2021-19. Echeveria ‘Silver on Red’ = Echeveria ‘Silveron Red’ R. Wright

Dick Wright has long been famous for his Echeveria hybrids. He apparently started hybridizing echeverias around 1958 and, at least in his later years, has employed a very simple technique for hybridization and selection. Hummingbirds are given free rein in his open-sided greenhouse, pollinating and hybridizing at will. Dick crumbles the mature carpels around the parent and later plucks out the most attractive seedlings for propagation. This selection, sometimes seen with the erroneously contracted name ‘Silveron Red’, was one of his earlier selections from 1966, and one with the richest coloration, alluded to in the cultivar name. The leaves are a rich purplish red with undulate margins in the distal portion and a silvery sheen caused by a thin layer of cuticular wax.
