Low to medium growing Quaking Grass (Briza media) is an asset to any style of garden. Whether you're aiming for a groomed, natural look or prefer formal gardening styles, this ornamental grass with its blue-green foliage and pert, upright habit is bound to fit in. It's at its very best from early summer when the pendulous, heart-shaped seed heads with a blush of pink appear. You'll want to add them to flower arrangements, and they're perfect for the purpose, whether you use them fresh or dry. The delicate-looking seed heads tremble in the breeze, giving this plant its English name.
