About plant names...
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 12-24" (30-60 cm) high and
about 12" (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.
