Crinkled Hair Grass is a cool-season ornamental that thrives where most grasses struggle: in the dappled shade of woodlands and under tree canopies. Native across North America, Europe, and Asia, this clump-forming grass reaches 24 to 36 inches tall and produces delicate, airy flower panicles that dance above fine, dark green foliage from July through September. It's one of the rare ornamental grasses that actually performs well in moderate shade, making it invaluable for gardeners working with less-than-ideal light. Hardy in zones 4 through 7, it combines drought tolerance with an elegant, textural presence that adds movement to shaded gardens.

Dark green, finely textured foliage forms a dense, low tussock, while summer brings wispy flower stems that rise to 3 feet, bearing wide, airy panicles with distinctive showy flowers. The grass handles dry shade beautifully, a rare trait among ornamentals, and its semi-evergreen character means it can provide winter interest when left standing. Unlike many shade plants that demand rich, moist soil, this species adapts equally well to dry conditions, making it remarkably low-maintenance once established.
Crinkled Hair Grass is grown as an ornamental, valued for adding textural contrast and movement to shade gardens. Its showy summer flower panicles serve as focal points or softening elements in landscape designs. The semi-evergreen foliage and persistent flowering stems provide year-round visual interest, and many gardeners leave the dried stems standing through winter for architectural appeal rather than cutting them back immediately.
No timeline data available yet for this variety.
Cut back all old foliage to the ground in late winter, before new shoots appear in spring. Flowering stems can be removed in fall if desired for a tidier appearance, or left standing through winter for architectural interest and winter wildlife habitat.

“Deschampsia flexuosa has a widespread natural distribution across the cool temperate regions of North America, Europe, and Asia, where it inhabits dry open woods, slopes, fields, and grasslands. Its presence across multiple continents suggests a long evolutionary history in cool-climate ecosystems. The common names "wavy hair grass" and "crinkled hair grass" refer to the characteristic appearance of its thin, arching, slightly inrolled leaf blades, which create a delicate, wispy texture that has made it increasingly valued in contemporary ornamental gardening over the past few decades.”
