Cultivar of the family Liliaceae (or Colchicaceae according to classifications), obtained by horticultural selection from species of the genus Tricyrtis originating from East Asia, mainly Japan and Taiwan, where the parent species grow in cool and shaded undergrowth, often on moist rocky slopes.
The plant forms an upright clump with arched stems, reaching 40 to 60 cm, bearing alternate, ovate-lanceolate leaves, bright green, with marked parallel veins, clasping the stem at their base. The foliage presents a neat and tidy appearance throughout the season.
The flowers are borne in the axils of the upper leaves and at the top of the stems. They are star-shaped, with six tepals spread out then reflexed at maturity, white to cream, densely speckled with purple-violet, with a yellow center and a very ornamental style, branched and itself spotted. This abundant and regular speckling, reminiscent of a leopard's coat, is the immediate visual signature of the genus Tricyrtis, which gives it the English name "toad lily".
Its flowering occurs in cultivation from August to October, bringing color at the end of the season in shaded situations. It requires a cool, humus-rich, well-drained but never dried out soil, in shade or partial shade, sheltered from cold winds.
