The leaves are large, four-lobed, with an entire margin; they become golden yellow in autumn, before falling. In late spring it produces numerous erect, tulip-shaped inflorescences, with yellow-green petals and orange center; in late summer it produces large pine cone-shaped fruits, consisting of many winged seeds, which fall in the autumn or the following spring.
