In the leaf axils are kidney-shaped stipules of up to 3.5 cm long, which the tendrils flank.

The alternately arranged leaves are tri-lobed with smooth edges and 5 to 9.5 x 5.5 to 14 cm.

The flowers are purple, bluish violet and white in color and 9–12 cm wide.

The corona consists of 6 or 7 rows, which are white at the base and above bluish purple.
