Vinegrass

This big, lime green grass grows up to 6 feet (1.8 meters) tall. The oblong stalks grow in extensive patches that are resilient and they are slow to spread and grow.

When mature, the end of the stem eventually transforms into a tiny, vibrant blue flower.

During the early summer, it produces very little pollen; it does not cause many allergic reactions, and after flowering, it is left with a modest amount of medium-sized grains.
