Sub-category: Aster family
Syn. Prenanthes altissima. Grows 2 to 6 feet tall and usually unbranched, except toward the apex where the flowerheads occur. The glabrous central stem is light green to purple. The alternate leaves are up to 8 inches long and 6 inches across (excluding the petioles), becoming gradually smaller as they ascend the central stem. They are quite variable in shape; the lower leaves are often divided palmately into 3 lobes (or less often 5 lobes), while the upper leaves often lack lobes (ovate or deltoid). The margins of the leaves are undulate, dentate, or entire (smooth). The upper surface of each leaf is medium to dark green and hairless, becoming yellowish green with age. The petioles are as long as the leaf blades or somewhat shorter. The foliage of this plant contains a white latex.
Found in forests with light shade, fertile loamy soil.
