Well, with those two guys practically (actually) telling you the name - congratulations to everyone who played!
The plant is Paph. Temptation (kolopakingii x philippinense)
Here were the clues:
1. I would only name one parent - a hint that it was a primary cross
2. Slow growing
3. Twisty petals
4. Multifloral (very)
5. Large plant (LS of 34 ")
Amazingly 2 people guessed it immediately. 2 others guessed after the additional clues from Hoa's questions.
Correct ID's : Tim (bench72), Jason (Jmoney), Julie (Piper), Hoa (Hoa Tony Nguyen aka Sir Speedo)
Soo - how about someone else posting a mystery plant we can all try to ID?
