|P. alata bears nodding, fragrant, bowl-shaped, bright carmine-red flowers, opening from light crimson buds. Produces pear-shaped, yellow fruit, 4 to 6 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. 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.
