| P. alatocaerulea bears fragrant, bowl-shaped, white flowers.
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. |
