Whitegrass

This massive, white and red grass grows up to 22 feet (6.7 meters) tall. The wispy stalks grow in sparse patches that are light and frail.

When mature, the end of the stem eventually transforms into a tiny, cream spikelet.

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