Crimson Grass

This large, lime green grass grows up to 6 feet (1.8 meters) tall. The long, tapering stalks grow in thin clumps that are flexible.

When mature, the end of the stem eventually transforms into a small, crimson flower.

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