Emerald Grass

This massive, emerald grass grows up to 18 feet (5.5 meters) tall. The wide stalks grow in large clumps that are light and frail and they spread and grow quickly.

When mature, the end of the stem eventually transforms into a tiny, cyan tuft.

During the mid-summer, it produces excessive amounts of pollen; it can cause severe allergic reactions, and after flowering, it is left with copious amounts of small grains.
