Yellowwind Grass

This big, yellow-green grass grows up to 5 feet (1.5 meters) tall. The thick stalks grow in thick clumps that are light and frail and they are exceptionally hardy.

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

During the late summer, it produces an average amount of pollen; it can cause severe allergic reactions, and after flowering, it is left with a handful of large grains.
