Violetgrass

This average-sized, violet or slate grass grows up to 2 feet (61.0 cm) tall. The long, narrow stalks grow in extensive patches that are resilient.

When mature, the end of the stem eventually transforms into a giant, black tuft.

During the early summer, it produces very little pollen; it can cause allergic reactions, and after flowering, it is left with a handful of small grains.
