Aqua Shield Grass

This large, gray grass grows up to 5 feet (1.5 meters) tall. The shield-shaped stalks grow in sparse patches that are light and frail.

When mature, the end of the stem eventually transforms into a medium-sized, aquamarine tail.

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