Rock Plates are rarely cultivated genera of ornamental plants with flat basal leaf rosettes and attractive pale-blue flowers in late spring. These are winter hardy relict species and occur in almost vertical rocks in the Pyrenees, the Alps, the Balkans to the Himalaya and require a shaded spot in a moist soil on peat basis. Best planted in North facing rock crevices in the rock garden. Sow on any humus and sand rich soil in pots outside. Do not cover seeds and place pots in a shaded spot and soil always moist. Carefully transplant in autumn as soon as seedlings are strong enough. All are USDA Climate Zone 6. 50 seeds per package. |
