Clinging Puffgrass

This short, lime green grass grows up to 1 foot (30.5 cm) tall. The wide stalks grow in thick clumps that are flexible and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a large, dark grey puff.

During the mid-autumn, it produces copious amounts of pollen; it can cause severe allergic reactions, and after flowering, it is left with lots of small grains.
