Mexican Feather Grass

Nassella tenuissima, more often known as Mexican Feather Grass is a common ornamental grass in Texas landscapes and still referred to Stipa tenuissima by some authorities. This perennial grass can reach 24” to 36” in height and 15” to18” in width. Ornamental grasses in general are grown for a texture and interesting foliage. Mexican Feather Grass has a light and airy texture consisting of green foliage with tan to cream plumes. This grass blooms throughout late spring to mid-summer. Hardy throughout most of Texas, Mexican Feather Grass is a great choice for a low to mid-level accent needing full sun and infrequent watering.20160626_172845

Mexican Feather Grass is one of my favorite grasses to use in the landscape because it provides movement as it sways in the breeze. Its graceful stems contrast with broad leaved succulents, bright flowers, and xeriscaping plants, such as Agave, Red Yucca, Lantana, Salvia, and even boulders and river rocks. Mexican Feather Grass works particularly well as a lining plant for pathways because the leaves and plumes fall over the edges of the path to provide a softer transition and immersive feel. It will self-sow freely which may be beneficial if used in large landscapes and meadows or even on slopes for purposes of erosion control. When used in containers and modern design it would be wise to deadhead the plant to control growth.

Maintenance at least once a year is suggested. Removing gray colored old growth is simple and will allow for more air flow between the healthy grass blades. I have found the best way to manage this is to run your fingers through the blades like you are detangling long hair. The dead growth will remove easily, and it will give you an opportunity to restructure the plant if you found it laying too far on one side.

*Warning: This plant doesn’t like soggy, wet soil and roots will rot in these conditions!!

We love to pair this plant with Agave, Soft Leaf Yucca, Gold Star Esperanza, Vitex, Salvia, Texas Sage, and other Texas Superstar Plants.

Other Names: Silky Thread Grass, Mexican Needle Grass
