Did you find the AOS culture sheet on Caularthrons? I had never heard of them before, but they don't sound too picky...

Well, I got my mini purple 'Blue Hawaii' forgiving cattleya and because it seems I have no self control when it comes to orchids, I asked the vendor if she had any other mini-type, easy-care cattleyas.
She sent me an adorable little Clty. Ethel's Paradise 'In Kalapana' . Caulocattleya? Of course I have never heard of caularthron orchids. The best information google comes up with . . .(was there any doubt?). . .is here at OrchidTalk. I know Bruce and Clint Dawley have them. Is this obscure cross some finicky princess best left to professionals? Am I doomed by my newbness to send it to the compost pile? Isn't it cute?
I think they have renamed some of the ones they used to call Dialaelia...to the Caularthron. (one of the members will know better than myself...i can't keep up with the name changes) I had a very lovely cross that lived to bloom for about two years, while I was a newbie. If I were you i'd be tickled to find one like that...don't overwater, but don't let your p-bulbs shrivel too much either. They like big chunky potting materials, with lots of air movement...and they are very forgiving. You found a nice one!
You will do great with it!! Have some faith and know we are all here if you need help along the way!
Your plant is lovely. It looks both delicate and beautiful.
Have fun caring for it.
Thats a gorgeous plant you got there ! Geneal care should be like most bifoliate cattleyas. Use charcoal chunks and coconut husk chips as the medium. They like slightly lower temperatures than standard catts. Home temperature should be ambient.
Caularthron is a small genus and used to be called Diacrium of which C bicornutum is best known. It is allied to the cattelya family and thus a few crosses have made with Laelia, Cattelya and Sophronitis. One of the characteristics of caularthron is that the flowers seldom open completely - a characteristic shown by the flowers in the picture you posted.
Any way congrats; the flowers are lovely and I like the dwarfish plant.
Very cute blooms!! Congrats-the plant and blooms are adorable!
