Peltoboykinia watanabei

Peltoboykinia Saxifragaceae

A splendid Japanese woodland perennial with a distinctly tropical air, Peltoboykinia watanabei produces large, shiny, rounded, peltate leaves that make a handsome architectural clump, rather like a miniature Rodgersia with considerably more Japanese restraint. In early summer, slender, upright stems carry loose panicles of delicate, pale yellow flowers above the foliage. Endemic to Japan, it is a plant of cool, damp woodland and mountain habitats, and should be grown in humus-rich, moisture-retentive soil in partial shade. Deciduous and reliably hardy, it is particularly effective planted amongst ferns and other choice woodlanders, where its bold foliage provides excellent contrast without becoming overbearing.
