Wow, they look happy! I have a big phal similar to those, and I'm not at home right now-so I can't go look at the tag-but looking at my list here I THINK it's Phal. DTPS. Blessed x brother sara gold (bs)....
Diane-how are you growing these, and how long have you had them? Did you repot when you they arrived?
I've had mine since June and it's sort of happy, but not THAT happy. I repotted to a plastic clear pot w/medium chc/bark mix. It was in an east window with a fair amount of morning sun, but now it's in a west window...not as much light.
