IPM1007, Revised November 2009
A herbaceous perennial vine with distinctive three-lobed leaves and attractive white and purple flowers that may reach 6-1/2 feet or more in length. Seedlings can occur but sprouts from perennial rootstocks are much more common. Seedlings have thick, oval cotyledons that are glossy in appearance. Mature leaves are arranged alternately along the stem, are slightly hairy, and are distinctly three-lobed (rarely with five lobes). Roots initially occur as a taproot but eventually develop a very deep perennial rootstock from which subsequent sprouts emerge. Mature plants have relatively large oval fruits that "pop" when they are stepped on, thus the name.
