Erysimum bicolor ssp. caldeiraoense ssp. nov. ined. Exclusive

Erysimum bicolor ssp. caldeiraoense ssp. nov. ined. Exclusive

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. hierrense subsp. nov. ined. Exclusive

Erysimum bicolor ssp. hierrense subsp. nov. ined. Exclusive

30 (50)cm, plants from El Hierro differ in various aspects from other populations, so that these merit a subspecies rank. Plants are short, dense woody shrubs with small terminal rosettes of short, narrow leaves and several short inflorescences with white flowers fading to lilac with age. Excellent pot plant which is easily cultivated in any rich, well drained soil in a sunny spot throughout the year. In winter keep drier at a minimum of some 10°C in full sun. For its high frost resistance it might be alternatively tried in a protected spot in the open garden in Central Europe. VI-VIII.

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.
