This is the result of crossing H. 'Niagara Falls' × a seedling (H. 'Silver Bowl' × H. 'Muriel Seaver Brown'). It was registered by Olga Petryszyn of Indiana in 1998. The plant forms a giant size mound about 28 inches high with a spread of 60 inches. Its leaves are heavily rippled, sometimes unruly and convexly cupped with deep lobes at the base. Near white flowers bloom from late June into July.

From the Field Guide to Hostas by Mark Zilis (2014), "Its combination of dome-like leaf shape, attractive rippling, and large mound size makes 'Hoosier Dome' a tremendous choice as a specimen plant."
