Muhlenbergia capillaris grows naturally in the clay and rocky soils of central and eastern North America, often in former prairie remnants and open savannas where periodic disturbance keeps taller vegetation in check. The specific epithet means hair-like, a fair description of the fine, wiry dark green leaves that form dense, arching clumps 2 to 3 feet tall. Through summer the plant is handsome but unremarkable; come September, long branching flower stalks rise above the foliage in a pink so saturated it reads almost luminous in afternoon light.

Pink muhly is among the most adaptable of native ornamentals, tolerating poor, dry, and rocky soils as readily as richer garden beds, provided drainage is good. It excels in mass plantings, where the combined effect of many plants in flower at once stops observers in their tracks, but even a single clump in a border delivers an unmistakable late-season moment. Cut back hard in late winter before new growth begins, and resist the impulse to divide too frequently, as established clumps flower most generously.
