Overview
Muhlenbergia lindheimeri is Lindheimer's muhly — the largest and bluest-foliaged Muhlenbergia, growing 36-60 inches (90-150 cm) tall with plumes and 36-48 inches (90-120 cm) wide. Named after Ferdinand Lindheimer, the 'Father of Texas Botany'. Blue-gray to silvery-blue narrow narrow-textured arching foliage — the most intensely blue of any Muhlenbergia species, providing year-round blue color. Tall silvery to pale purple airy plumes in October and November. Native to Texas Hill Country limestone grasslands — giving extreme heat, drought, alkaline soil, and rocky condition tolerance. The largest Muhlenbergia for substantial blue architectural presence — significantly larger than M. capillaris (pink muhly) and M. reverchonii (seep muhly). Semi-evergreen in mild winters. Hardy to zone 6.
