Scientific Synonyms:

Avenella flexuosa

Description

Deschampsia flexuosa is an elegant, fine textured, clumping, evergreen ornamental grass. The delicate yet densely produced arching deep-green leaves form neat mounds up to 1' tall and the same across. In mid to late spring it produces an abundance of flowering stems up to 30" tall. The flowers are long-lived, forming delicate feathery clusters that will remain attractive long after they have set seed, often persisting well into winter.

Cultivation

Wavy hairgrass is exceptional among ornamental grasses because of its high shade tolerance. Flower and seed set are better with more light, but this is a cool season grass and it will suffer in full sun, or even part-sun in areas warmer than zone 7. Perfectly adapted to the mesic conditions of our deciduous woodlands, it thrives in rich, well-drained soil and has the ability to withstand extended dry spells, particularly if grown in a shady location. This is one of the few ornamental plants that not only remains attractive in dry shade, it will thrive there. It is an effective ground cover when planted in groupings, and is equally attractive when grown as a specimen. It might spread by seed in disturbed areas, but is otherwise well behaved and tends to stay in place. A good haircut in late winter, before new growth emerges, will maintain a neat appearance. Zones 4-8

Propagation

Propagate from seed, or by clump division in late winter and early spring.

Additional Notes

An excellent alternative to English ivy, Liriope, and other introduced invasive species commonly used in dry shade.
