Erysimum bicolor ssp. caldeiraoense ssp. nov. ined.

Erysimum bicolor ssp. caldeiraoense ssp. nov. ined.

100 (180)cm, tall, evergreen shrub with a woody base and narrow, ascending branches. Native to moist, partially shaded spots in the laurel forest region of Madeira, very rare in its habitat (e.g. Caldeirao Verde at some 920m). Originally included in Erysimum bicolor from the Canaries, yet as it is quite different in various aspects, it merits a species rank. Among others it is a hexaploid species. Makes strongly serrated, long lanceolate leaves and white to purplish-pink flowers. For any humus rich, slightly moist soil in a sunny spot. Keep slightly drier and always sunny in winter. IV-VI.

Erysimum bicolor ssp. ruivoense ssp. nov. ined.

Erysimum bicolor ssp. ruivoense ssp. nov. ined.

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.
