|Xanthorhiza simplicissima is a tall and even groundcover, 2-3 feet in height. It spreads by suckering from the roots, has erect stems with celery-like foliage and provides a thicket of growth. Excellent for difficult shady ground. Foliage is bright green in summer, attractive, may develop orange and yellow fall color. Leaves persist on the plant into winter. Flowers are not showy but provide interest: brownish purple, small, star-shaped on 2-4 inch racemes, usually appearing before the leaves in early spring. Plant divisions in spring or fall. Will develop chlorosis in high pH soils, but has no real pests. The name "Yellowroot" comes from the deep yellow inner bark and root. Native from New York to Florida.
