This erect, rhizomatous perennial grows to a height of 12-24 inches. The largest of the deeply cleft leaves are 2-4 inches wide and the flowers may be 1 inch or more across. The flower has lines on the petals called nectar guides which point to the center. This supposedly helps pollinating insects find their way to a meal.
Native to the eastern US, these plants grow in alluvial woods and in rich coves and bloom from April through June.
