Panicum virgatum ‘Red Flame’- Switchgrass

From Walters Gardens:

A boldly colored grass with native roots, ‘Red Flame’ is primed to set your garden ablaze in late summer. This warm season grass emerges with blue-green foliage before turning almost completely wine red by summer’s end. Compared with classic varieties like ‘Shenandoah’, ‘Red Flame’ has a greater saturation of red color on each leaf and incredible vigor. Use this grass for its color, texture, and durability in the landscape.
