Leaves are generally semi-evergreen, made up of 3-9 lanceolate or ovate leaflets that are deep green during the growth period, and change color to purple-green in autumn. Flowers of 5-10 cm across are set singly on long stems (10-15 cm) growing out of leaf axils. They comprise 4 to 8 oval, slightly wavy edged tepals which are creamy white and have a pale green central bar on the outer side. In autumn flowers turn slightly greenish.The striking appearance of the blooms is due to its unusually long contrasting stamens consisting of deep crimson-purple, almost black anthers set on filaments that are white at the base and violet at the top.
