Crimson Grass

This colossal, red grass grows up to 35 feet (10.7 meters) tall. The wide stalks grow in thin clumps that are robust and they spread and grow quickly.

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

During the late autumn, it produces very little pollen; it can cause allergic reactions, and after flowering, it is left with a handful of giant grains.
