Description
A robust, hairy perennial herb up to 60 cm tall, with tubers. Basal leaves subcoriaceous, up to 30 cm wide, orbicular-cordate, with shallow lobes, while the upper leaves are much smaller, lanceolate and entire. Flowers yellow, glossy, sometimes with whitish spots on the petals, up to 5 cm across, arranged in subcorymbose inflorescences. Achenes smooth, black when ripe, with a persistent style.
Propagation and growing
Propagation by seed. The best germination rates (60%) are obtained at 15ºC, decreasing as temperature rises until reaching zero at 26ºC. Sowing in autumn is therefore recommended. Germination in standard substrate with some humus-rich soil added. Surface broadcast sowing.
Garden use
A plant for woodland edges and semi-shaded spots within the potential range of the monteverde (laurel forest). Low maintenance; give supplementary watering if winter rainfall is scarce. Do not water during the dormant period, which falls in summer. A perennial with showy spring flowers.
