Flamegrass

This enormous, orange grass grows up to 28 feet (8.5 meters) tall. The wispy stalks grow in large clumps that are light and frail.

When mature, the end of the stem eventually transforms into a large, blood red tuft.

During the mid-summer, it produces lots of pollen, but it does not cause any allergic reactions, and after flowering, it is left with excessive amounts of medium-sized grains.
