Graygrass

This small, gray-green grass grows up to 1 foot (30.5 cm) tall. The circular stalks grow in thick clumps that are rigid.

When mature, the end of the stem eventually transforms into a large, cyan flower.

During the early autumn, it produces lots of pollen; it does not cause many allergic reactions, and after flowering, it is left with lots of medium-sized grains.
