The stems can be smooth or pubescent; they are long and trailing, possessing many tendrils. Leaves are alternate and palmately 3-lobed, measuring from 6-15 cm. They have two characteristic glands at the base of the blade on the petiole. Flowers have five bluish-white petals. They exhibit a white and purple corona, a structure of fine appendages between the petals and corolla. The large flower is typically arranged in a ring above the petals and sepals.
