Vinegrass

This small, cyan grass grows up to 1 foot (30.5 cm) tall. The circular stalks grow in large clumps that are durable and they are exceptionally hardy.

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

During the mid-autumn, it produces very little pollen, but can cause severe allergic reactions, and after flowering, it is left with copious amounts of small grains.
