Silvergrass

This average-sized, gray grass grows up to 3 feet (91.4 cm) tall. The very thin stalks grow in large clumps that are prone to bending and snapping under stress and they overwhelm an area rapidly.

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

During the early summer, it produces an average amount of pollen; it does not cause many allergic reactions, and after flowering, it is left with excessive amounts of small grains.
