Briza Grass is often called Quaking Grass, because of its long stems and small leaves that run much of the length of the stem and grow small pods that move when the wind blows. This grass measures between 12 and 24 inches. With the leaves and pods it has a fantasy appearance that gives the arrangement it is added to a special appearance that is not found with other grasses in floral arrangements. There is also a mini Briza Grass that has the same appearance, although it does not grow as large.
