Giant Water Grass

This colossal, lime green grass grows up to 8 feet (2.4 meters) tall. The finger-like stalks grow in small clumps that are flexible and they are slow to spread and grow.

When mature, the end of the stem eventually transforms into a small, bronze flower.

During the early winter, it produces an average amount of pollen; it can cause allergic reactions, and after flowering, it is left with a few giant grains.
