This snakeroot has 3- to 5-inch-long leaves that are sharply toothed on the margins. Best of all, they are a subtle brown-maroon color. Late in the summer, many small heads of tiny white flowers open on top of the erect stems. The flowers resemble annual ageratum in shape and texture. After blooming, the plant develops seedheads with soft white hairs. This plant will grow even in deepest shade, making it indispensable in the woodland garden with its bright white flowers. It is also attractive as a focal point in the perennial border. A uniquely colored plant for shade gardens
