Goldgrass

This giant, lime green grass grows up to 12 feet (3.7 meters) tall. The V-shaped stalks grow in thick clumps that are robust and they are slow to spread and grow.

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

During the early summer, it produces very little pollen, but can cause severe allergic reactions, and after flowering, it is left with lots of large grains.
