This densely-bunched grass was introduced to the U. S. from Asia for ornamental
purposes in the late 1800s. Today some 50 forms are sold in the nursery trade, and
it is often used in both commercial and residential landscapes. Unfortunately, it
escapes from these plantings and has become invasive in national parks in
Virginia, North Carolina, and Tennessee.
