|P. x caeruleoracemosa bears bowl-shaped, red-purple flowers, and produces ovoid green fruit, up to 2 1/2 inches long.
This evergreen to semi-evergreen vine dies back to the ground in colder areas, but can remain if well mulched or planted in a sunny location that rarely, if ever, freezes. Leaves are five-lobed and flowers are slightly smaller, but with the same stunningly beautiful flower and edible fruit. Prune out inner growth periodically to keep plant open and healthy. This hardy climber does so by tendrils and is a favorite food of caterpillars and fritillary butterfly. Wonderful over a trellis as a shade-providing option or as a slope stabilizer, tropical selections can be grown as houseplants in a very bright window.
