Crimson Stalk Grass

This huge, pink-red grass grows up to 34 feet (10.4 meters) tall. The fan-like stalks grow in thick clumps that are resilient and they spread and grow quickly.

When mature, the end of the stem eventually transforms into a tiny, bright yellow flower.

During the mid-autumn, it produces very little pollen; it can cause allergic reactions, and after flowering, it is left with plenty of tiny grains.
