Magnolia wilsonii

Wilson's Magnolia, Oyama Magnolia

Origin:  The genus Magnolia is named after Pierre Magnol, a French botanist who lived from 1638 to 1715. Native to China, found in the eastern provinces of Guizhou, Sichaun and northern Yunnan. Discovered by the great plant hunter E. H. Wilson in 1904 but it was not introduced into cultivation until 4 years later when he managed to collect seed.
