Bluegrass

This large, green grass grows up to 6 feet (1.8 meters) tall. The thick stalks grow in small clumps that are resilient.

When mature, the end of the stem eventually transforms into a medium-sized, muted blue tail.

During the mid-autumn, it produces very little pollen, but can cause severe allergic reactions, and after flowering, it is left with lots of medium-sized grains.
