Brand: Rocalba
Medium-sized variety. Medium green foliage, medium width (15 mm), with very split and jagged edges. The leaves are arranged upright, and thus form a funnel, not forming a heart. CROP: cold resistant species. Soils of light or medium consistency, rich in organic matter. Tying or covering the plants will improve the bleaching of the inner leaves (duration: 2-3 weeks).
