A variation of 'Karl Foerster' feather reed grass, this variety is almost identical in shape, but 'Eldorado' has golden-yellow midribs. It's seed heads have a golden yellow hue. It grows upright in stiff clumps that keep their shape through the year. They grow only to 5 or 6 feet tall, making them one of the most manageable ornamental grasses for the home landscape.
