About Big Blue Stem

Andropogon gerardii 'Karl's Cousin' is a distinguished native grass cultivar known for its tight, upright, and architectural habit. Often called the 'Karl Foerster' of big bluestems, it resists flopping even in rich soils. The foliage emerges in a striking blue-green hue, transitioning to deep shades of purple and wine as the season progresses. It produces showy flower heads in late summer that provide interest through winter. This resilient, drought-tolerant grass thrives in full sun and is ideal for narrow spaces or vertical accents.
