Mauro, I really like those Laelias. I can't call them sophronitis or cattleya, they will always be "rupicolous" Laelia to me.

I'm growing L. cinnabarina and L. flava, and another one that is unifoliate, but never bloomed. Do you know if some of this kind of Laelia need some low temperatures to bloom?
May be this is my problem with the third one, because the plant is growing great, but any flowers..

Hugs!

Yes, most of them need low temperatures during the night, especially L. briegeri, bahiensis, pfisterii etc.
But, if your plant is growing great and is adult already then you should look for another cause. Maybe light level? Most of them need very bright light the year round to flower.
