Olivegrass

This big, olive and lime grass grows up to 6 feet (1.8 meters) tall. The 4 pointed stalks grow in small clumps that are strong and tough and they spread and grow quickly.

When mature, the end of the stem eventually transforms into a small, green tuft.

During the early autumn, it produces a fair amount of pollen; it can cause allergic reactions, and after flowering, it is left with plenty of giant grains.
