Tailgrass

This large, yellow-green grass grows up to 4 feet (1.2 meters) tall. The 7 pointed stalks grow in thin clumps that are rigid.

When mature, the end of the stem eventually transforms into a large, brown tail.

During the late autumn, it produces lots of pollen, but it does not cause any allergic reactions, and after flowering, it is left with a few tiny grains.
