Robust photosynthetic plants similar in appearance to clump grasses. They have a shallow but complex root structure, which requires a solid surface to produce structural stability. Clumps may form through tillering or wider dispersal through a variety of seeding mechanisms. Some species have adapted cellular structures containing high sugar concentrations to protect against freezing damage.
