Waterstem Grass

This average-sized, moss green grass grows up to 3 feet (91.4 cm) tall. The needle-like stalks grow in extensive patches that are flimsy and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a medium-sized, orange puff.

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