( Green Mountain Hosta ) The large hostas are 24" high by 40" wide. The hosta plants form mounds of medium green foliage with wide margins of streaking white. Leaves are quite large at 11" by 9" and are smooth and wavy with good substance. Near white flowers on 28" scapes in mid summer. Showy white margin on a nice large hosta specimen.
