Muhlenbergia dubia – Pine Muhly

Bring fine texture and upright structure to sunny borders with Pine Muhly.

Muhlenbergia dubia is a compact, warm-season ornamental grass that forms dense clumps of narrow green foliage. Slender flower stalks rise above the leaves in late summer and fall, adding light, airy movement before maturing to warm tan tones. Repeat Pine Muhly along a pathway or pair it with bold-leaved plants and flowering perennials for a pleasing contrast in texture. Its manageable size makes it useful in smaller dry gardens, while its heat and drought tolerance once established suits sunny, well-drained planting sites.
