Mexican feathergrass is native to Texas, New Mexico, Mexico, and Argentina.
Increasingly popular as an ornamental grass, it is potentially invasive in some areas.
Identification: This grass forms clumps 1-2′ (30-60 cm) high and
about 1′ (30 cm) around. Feathery green flower clusters 6-12″ (15-30 cm) tall mature to silvery tan in color.
The individual flowers each have a long, thin awn 2-3″ (5-7.6 cm) in length. Grass blades are
6-14″ (15-35 cm) long,
almost tubular, tightly rolled, making the blades appear very fine, only half a millimeter in diameter.
The tan-colored panicles of flowers are several inches long. · 8/1/2009 · Coastal Maine Botanical Gardens, Boothbay, Maine · ≈ 2 × 1′ (58 × 38 cm)
