Silverstem Grass

This large, silver grass grows up to 7 feet (2.1 meters) tall. The thick stalks grow in large clumps that are flexible and they are exceptionally hardy.

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

During the mid-autumn, it produces an average amount of pollen; it can cause severe allergic reactions, and after flowering, it is left with a modest amount of tiny grains.
