Erysimum bicolor ssp. ruivoense ssp. nov. ined. Exclusive


Erysimum bicolor ssp. ruivoense ssp. nov. ined. Exclusive
50 (100)cm, low, evergreen shrub with a broad woody base. Native of subalpine regions of Madeira (e.g. below Pico Ruivo at some 1.720m), where it is rather rare. Has short, narrow, leathery leaves, with slightly serrated margins. As the species described above, originally it was included in Erysimum bicolor from the Canaries, yet as it is quite different from the latter as well as it has a completely different habitat than Erysimum caldeiraoense sp. nov. ined., it merits a species rank. Flowers open cream and turn to rich light purple. For any well drained, rather rocky soil in a sunny spot, keep sunny in winter. Maybe tried in the open garden in a winter rain protected, sunny spot. USDA Climate Zone 9. IV-VI.
