Briza–commonly called quaking grass or rattlesnake grass–is a delicate, graceful ornamental grass with linear leaves and loose racemes or panicles of flower spikelets that hang from very fine stalks and as a result quake and flutter in the slightest breeze. The spikelets resemble rattlesnake rattles.
Use quaking grasses in mixed plantings, or grow them in rows in the cutting garden to produce stems for drying. Briza grows best in full sun to light shade and average to rich soil that is well-drained.
Briza is a genus of more than 12 ornamental grasses, both annuals and perennials. Briza is native to open scrub and grassland in temperate Europe and Southwest Asia.
