Whoa, that is such a disappointing let down. The feeling of accomplishment you must have felt when the spikes and buds started showing along with the anticipation of seeing and sharing the flowers, only to end up with this. Nice flowers as you said, but also a bit of a dud if it took 16 years to bloom. I'd be employing some deep breathing techniques because what else can you do?
Is this typical for In Charm (i.e. mislabeled plants)? 15+ years ago, I feel like they had a great reputation in the USA, but more recently I get the impression that they've burned some bridges and destroyed a lot of good will. Then again, maybe I'm misremembering?
Any ideas what you'll do with this plant? I'd almost have to part with it purely because it would end up being a reminder of the disappointment, but I could also see keeping it and making the best lemonade you could from the situation.
I'm always so tempted by the multifloral (ex: roth) x parvi hybrids because the flowers can be so incredibly stunning and I don't get to see them very often. It just seems like a hassle to bloom them reliably and the gorgeous foliage is nice to look at but if that's what I was after, I can find plenty of Paphs (and orchids in general) with foliage that's even more attractive.
