River Mist Northern Sea Oat Grass

Chasmanthium latifolium 'River Mist' PP #20,643

A warm-season grower, upland sea oats are especially valued for their graceful, hanging "oats" held on slender, nodding foliage. Tan seed heads emerge in summer and remain as attractive white ornamentation from midsummer through winter. A showcase plant, this striking green and white foliage form will make a fantastic specimen.
