Mexican feather grass. The thread-like, bright green leaves of this ultra fine-textured grass form soft clumps to 2 or 3’ high. Pliant, nodding panicles on slender stalks open bright green in late spring, then age to gold and finally bleach to creamy-white by fall. These feathery clumps wave gracefully in even the slightest breeze and offer drama and elegance to the garden, especially when combined with dark-leafed plants like Rhamnus ‘Leatherleaf’ or some of the darker Phormiums. Use singly or scattered in clumps as an effective groundcover, among boulders, or on slopes for erosion control. Prefers fertile well-drained soil in sun or partial shade with moderate garden water. Mexican feather grass self-sows invasively in gardens with constant moisture, but much less aggressively in dry gardens. Hardy to 0F. Southwestern United States, Mexico, and Argentina. Formerly Nassella tenuissima.
