Watching paint dry

[Nero]

Or I might just watch this

 

[Vinny]

Most likely a species of Selenicereus, maybe S. wittii. A few species are not uncommon in cultivation but they pretty much all produce huge, long rambling growths, not unlike rambling roses, so aren't especialy popular wherever they must be grown under glass, frost-free. The flowers are mostly large - 6 inches and some quite a bit more, across, mostly white and mostly very heavily scented. But last just one night.
I'm not sure if they are moth or bat-pollinated, that may depend on species.
