Coppergrass

This big, brown or copper grass grows up to 5 feet (1.5 meters) tall. The very thin stalks grow in thin clumps that are robust and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a small, florescent blue tuft.

During the late summer, it produces excessive amounts of pollen, and after flowering, it is left with a handful of tiny grains.
