Briza media is a rhizomatous, creeping, warm-season ornamental grass that features a clump of narrow, erect, green leaves, typically growing up to 15 inches (37.5 cm) tall. Tiny, greenish flowers appear in spring in loose, airy panicles atop stems rising well above the foliage clump up to 3 feet (90 cm) tall. Flowers give way to flattened hop-like, purplish-maturing-to-tan seed heads which dangle on thread-like stems and quiver in the slightest breeze, thus giving rise to the common name.

How to Grow and Care

Quaking Grass has no special germination requirements and so can be sown at any time of the year to raise plants. As with most grass seed, this means that seed can also be sown successfully in open ground in both autumn and spring.

It is slow-growing grass and so will take time to establish from seed.  It is best sown in small quantities to add interest as a minor component of a mixture, with the main ground cover provided by other companion grass species.

As Quaking Grass is not a very competitive grass, it does require good grassland management (mowing and grazing) to maintain its presence in a mixed sward, particularly on better soils. Neglect or even regular late hay cutting will allow taller grasses the opportunity to outgrow and to shade it out. Also, while quaking grass does produce side shoots, it does not spread laterally very much, so is dependent self-seeding into gaps created by good management to maintain itself or increase in a mixed sward.
