A pretty Japanese plant with narrow strap-like leaves longitudinally banded with creamy-white or yellow bands. At one time it was grown freely for market, and is still grown by several for its ornamental appearance. It is almost hardy, and grows in loamy soil, and may be increased by division. Other kinds are japonica, with a variegated form, and spicata, with broader leaves and lilac flowers.
