A herbaceous species growining on woodland margins in Hokkaido, Japan. Very early flowering, the first blooms appear at ground level (get eaten by slugs) and then the later blooms appear as the stems lengthen. Probably requires a dry winter rest and a hot summer, but I will do my best anyway.

I bought it from Edrom Nursery and their label says:

"A woodlander with finely cut ferny foliage which emerges in late winter/spring marginally before the bowl shaped buttercup yellow occasionally bronzed flowers, 20cms. Hokkaido, Japan." Wim Boens writes in 'The Plantsman':

"this species is endemic to Japan where its range overlaps with that of A. amurensis, A. multiflora and A. shikokuensis. Mostly found growing at the margins of deciduous forest, it is assumed that it originally arose from a cross between A. multiflora and A.shikokuensis.
The finely dissected leaves emerge bronze and it flowers at a height of about 15cm, extending to 35cm afterwards. Each stem can bear several flowers. The leaves die back in June."

Chicago Botanic Garden says:

"At the beginning of March in Japan, 10,000 people come to the park where Adonis has naturalized. The sunny little yellow flowers may be just 1 1/2 inches in diameter, but there's a carpet of them...thousands and thousands. It's the first sign of spring. And once bloom is done, the ferny mounds of foliage unfold.
Members of the Adonis family can be found from Sweden to North Africa to Japan. Some are perennial, spreading by rhizomes or stolons; others are annual. While they're generally happiest in part shade, many are fine in full sun with enough moisture. However, as natives of rocky areas, hillsides, and loose forest soils they do insist on good drainage."
