Puffgrass

This average-sized, green grass grows up to 3 feet (91.4 cm) tall. The perforated stalks grow in small clumps that are resistant.

When mature, the end of the stem eventually transforms into a small, beige puff.

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