Coppergrass

This small, copper grass grows up to 1 foot (30.5 cm) tall. The circular stalks grow in thin clumps that are strong and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a giant, lime puff.

During the mid-autumn, it produces lots of pollen,but it does not cause many allergic reactions, and after flowering, it is left with a few large grains.
