Coppergrass

This average-sized, copper grass grows up to 2 feet (61.0 cm) tall. The long, narrow stalks grow in thin clumps that are flexible and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a small, red puff.

During the late autumn, it produces a modest amount of pollen; it can cause allergic reactions, and after flowering, it is left with a modest amount of giant grains.
