Mexican feather grass (Nassella tenuissima, formerly Stipa tenuissima) is a clump-forming, cool-season grass that greens up early in spring and begins flowering by early summer, with silvery tops that turn golden blond as the summer progresses and the seeds mature. In fall, the glossy, bright green foliage turns light tan and lasts through the winter, until you cut it to the ground in spring, giving the plant a true-four-season presence. The foliage and slender, arching stems are so fine that they sway in the slightest bit of wind, adding a wonderful sense of movement to the garden. Mexican feather grass clumps generally reach just 1 to 2 feet tall and look great paired with other low perennials, planted around the base of taller companions such as Brazilian vervain (Verbena bonariensis), or used as a soft edging for a path or border. It also grows beautifully in a container. Full sun. Perennial; Zones 6 or 7 to 9.
Collected in early July 2023. At least 30 seeds. Be aware that Mexican feather grass may self-sow and is considered invasive in some regions. If you are concerned about that in your area, consider growing the native prairie dropseed (Sporobolus heterolepis) instead for a similar effect.
