Ambergrass

This average-sized, orange grass grows up to 1 foot (30.5 cm) tall. The slender, pointed stalks grow in sparse patches that are strong and tough and they overwhelm an area rapidly.

When mature, the end of the stem eventually transforms into a medium-sized, lilac flower.

During the mid-autumn, it produces a modest amount of pollen; it does not cause many allergic reactions, and after flowering, it is left with lots of giant grains.
