Coppergrass

This short, copper grass grows up to 1 foot (30.5 cm) tall. The finger-like stalks grow in thick clumps that are resistant and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a medium-sized, slate flower.

During the late summer, it produces an average amount of pollen; it does not cause many allergic reactions, and after flowering, it is left with lots of large grains.
