Original, Japanese cultivar of double flowers 11-14 cm in diameter, consisting of about 60 sepals. Sepals lanceloate, pointy, with slightly wavy edges and tips pointing downwards. Light green with pink-toned tips when in buds, turning white when opening. In full bloom white, sometimes with greenish bar along the middle, greenish margins and pinkish tips. Same coloured on both sides.  Usually under the flowers there are 6-12 bracts on long leaf petioles. Cream-coloured stamens are visible only in full bloom. Flowers are borne on previous year wood, nearly from the very base up, between second half of May till June. Dark green leaves are single or trifoliate. New shoots are purple. The plant reaches 1.5 m height. Climbs by leaf petioles.

It is useful for growing over low garden supports or in containers kept on a balcony or a terrace. Thrives in well-lit sites.  It looks particularly attractive against dark background.
