Vertical backbone for large spaces — creates height and rhythm that gives prairie-style and naturalistic plantings real structure.

Dramatic fall color shift — foliage deepens into dark purple-black tones as the season winds down.

Nativar selection — maintains the ecological strength of native big bluestem while elevating visual drama.

Returns with presence each year — reestablishes on schedule and grows into a commanding, repeatable form.
