Generous Orchid Society

[Laticauda]

I joined the local Orchid Society and every time I go, they send me home with another beautiful orchid. I feel very blessed to be involved with this group.

Here's the rub though: the plant they gave me is not easy to find information on it. Its label says "Epicat Moonmist 'John Ward.'"
I assume this is a hybrid between an Epidendrum and a Cattleya. Is Moonmist the Grex name?

I was just going to take care of it like a Cattleya. Does anyone have this one so I can see the flowers? When is it supposed to bloom? Does it need a dormancy? Does it prefer to be potted in bark mix or what?
Any other information very welcome. Here's a picture.
