Coppergrass

This big, moss green grass grows up to 6 feet (1.8 meters) tall. The perforated stalks grow in sparse patches that are sturdy and flexible.

When mature, the end of the stem eventually transforms into a tiny, copper tail.

During the mid-autumn, it produces very little pollen; it does not cause many allergic reactions, and after flowering, it is left with plenty of small grains.
