Briza maxima, commonly known as big quaking grass, is an annual herb native to grasslands and open areas in the Mediterranean region, including Northern Africa, Western Asia, and Southern Europe. It has become naturalized in various parts of the world, such as the British Isles, the Azores, Australasia, the western United States, Central and South America, and Hawaii. This grass typically grows to a height of 12 to 24 inches (30 to 60 centimeters) and features delicate, nodding flower heads that are highly ornamental. The flower heads are large, airy, and heart-shaped, with a green to purple hue, blooming in late spring to early summer. The flowers are quite showy and are often used in dried flower arrangements due to their unique appearance and ability to retain their shape and color when dried.

Big quaking grass is valued for its distinctive, quivering flower heads that add movement and texture to garden designs. It is often used in meadow plantings, as an accent in borders, and for naturalistic landscaping. It prefers full sun to part shade and thrives in well-drained soils. While it is drought-tolerant once established, it benefits from regular watering during prolonged dry periods. It is generally low-maintenance, but it can self-seed prolifically under favorable conditions. Gardeners should be aware of its potential to become invasive outside its native range and take steps to control its spread if necessary.CC BY-SA 4.0
