Try a Native-Northern Sea Oats
Northern sea oats (Chasmanthium latifolium) is an ornamental grass that grows 24"-36" high in loose clumps of green foliage. Its name derives from its seed pods, which look like oats. This deer-resistant ornamental grass is cold hardy to zone 5. Should you wish to mass together several clumps of an ornamental grass variety in the middle row, northern sea oats would be an excellent choice.
