This incredible hybrid of H. montana ssp. macrophylla has the same huge deeply-veined green leaves that arch outward on graceful 3' stalks. A mature clump should reach 5' in width. In late spring, the clumps are topped with stalks of white flowers...MAGNIFICENT! H. 'Jade Cascade' was the winner of two of the top awards at the 1996 American Hosta Society convention in Portland.
