The domed, heart shaped leaves of Cathedral Windows glow from a golden-yellow interior. The wide, dark green leaf margin is significantly wider than the parent plant, Stained Glass. Essentially a bright yellow version of Holy Moly. Cathedral Windows is crowned with large fragrant near-white flowers in late summer. Bright filtered light draws out the best coloration on this vigorous grower. My personal opinion of this hosta is it is just gorgeous. Introduced in 2005 by Hans Hansen. Patent Pending Hosta.
