'Empress Wu' Plantain Lily is considered the largest Hosta available. The enormous green leaves are corrugated and have a faint blue coating in spring. Lavender flowers appear above the foliage in July and August, often attracting Hummingbirds. Hosta 'Empress Wu' is a seedling of Hosta 'Big John', which was bred by Brian and Virginia Skaags. Be patient, as it takes several years for 'Empress Wu' to reach its final amazing size. Named after the only female empress of China (624 AD to 705 AD).
