Catleya Orchid...Don't know the name but it is hardy!
There are so many out there it will be nigh on impossible to say what c.v. it is from a photo (not that I'm good enough to say what it is in real life either *G*!)
It stays outside year round in temps that top 48C in the summer! I do nothing but water and fertilize!
Chamma I dont know where you like. you mustnt get frost so it is hardy where you live but it's not a hardy plant. a few degrees below and it will turn to mush.
I meant it was hardy for my area..alot of orchids don't survive the summers here
