Cut leaf Daisy

The several stout stems of this perennial grow 2 ft. tall and are branched above to form a rounded crown. Long-stalked, yellow, eight-petaled flowers open in late afternoon then fold under in intense heat and sunlight the next day. There are few to several flowers in the terminal clusters about 1 1/2 inches across. The 8-10 ray flowers are 1/2 inch long and are indented at the tip. The deeply cleft and toothed leaves are mostly basal, forming a large clump or winter rosette.
