northern sea oats

Chasmanthium latifolium (northern sea oats) is a native grass that produces unique, large seedheads that can be left through winter to add interest to the garden.

The foliage changes color from a blue-green when it first emerges to a vivid green before fading to brown. C. latifolium reseeds easily and therefore can be aggressive if left unchecked. A larval host plant for the Northern Pearly-Eye butterfly.
