Graygrass

This modest-sized, gray-green grass grows up to 2 feet (61.0 cm) tall. The very narrow and elongated stalks grow in thick clumps that are flexible.

When mature, the end of the stem eventually transforms into a tiny, black puff.

During the late autumn, it produces a fair amount of pollen; it does not cause any allergic reactions, and after flowering, it is left with lots of medium-sized grains.
