Ambergrass

This small, orange-yellow grass grows up to 1 foot (30.5 cm) tall. The circular stalks grow in thick clumps that are flexible and they are exceptionally hardy.

When mature, the end of the stem eventually transforms into a medium-sized, beige tuft.

During the mid-autumn, it produces a modest amount of pollen; it can cause severe allergic reactions, and after flowering, it is left with lots of giant grains.
