Chasmanthium latifolium, Northern Sea Oats

Tried and True Native Plant Selections for the Mid-Atlantic

This beautiful, tall woodland grass* grows in upright clumps and produces fresh green leaves that are held perpendicular at intervals on stiff, wiry culms (hollow stems). Spangled over drooping culms that stand well above the foliage, the eye-catching oat-like seed heads rustle and shimmer in the breeze.
