The original seed came from the area of the Yungi temple in China in 1980, in the Zhejiang Province, where it grows abundantly. It has upright stems, broadly ovate leaves and upright clusters of flowers with reflexed petals, heavily reddish speckled, 3-4' tall, with profuse flowering both terminally and in the leaf axils. Unusual yellow flowers in late summer. This is a tall plant with quite showy flowers which are borne well above the foliage on fine stems. The flowers have large irregular spots, thicker towards the tips of the petals.
Flowers are a medium yellow, peppered with small red spots.
Leaf backs are a darker purple. Tricyrtis 'Sharkskin' is a selection of T. stolonifera. It is even more iridescent than the cultivar 'Amethystina' and a very vigorous grower. The coloration and sheen reminded me of those ridiculous sharkskin suits that were worn in the 1960's. Great with Hostas.
