Very, very pretty, Ursula! And beautifully mounted as well!
I've got several Phals blooming now, but only this one has an ID...Phal 'Sogo David'...Opened it's 1st bloom, with several more to come.
Funny thing about this one...I had him mounted last Spring on some drift wood, and he never was happy, or even started attaching roots, so I moved him back into a pot, and he seems so much happier.
Oh well...Growing like crazy now!
