Grasses
Chasmanthium latifolium
Northern sea oats
Flat, dangling seed heads tremble in a breeze above broad, bamboo-like leaves. Their changing green, tan and purple tones add interest from summer into fall, while the foliage can turn golden. This native grass is useful in moist, partly shaded naturalistic plantings, but needs room or regular control because it spreads and self-sows.
