Coppergrass

This big, copper or purple grass grows up to 4 feet (1.2 meters) tall. The very narrow and elongated stalks grow in extensive patches that are sturdy and flexible and they spread and grow quickly.

When mature, the end of the stem eventually transforms into a medium-sized, silver spikelet.

During the mid-autumn, it produces an average amount of pollen; it does not cause any allergic reactions, and after flowering, it is left with a few medium-sized grains.
