Zygopetalum Trozy Blue

[callym]

Hi,
Earlier this year, I got a really lovely orchid labelled Zygopetalum Trozy Blue from Burnham Nurseries, during the Glasgow Orchid Fair. It flowered for months and had a really beautiful fragrance, and seems to be happy enough at the moment.

The other day, I found orchidroots.com, and was trying some of my orchids in it to see what information I could find about their genetics etc (just for curiosity really!), but couldn't find my Zygo there, then I tried Google and only found online houseplant shops, I even tried the AOS archives and couldn't find anything.

So now I'm trying here - does anyone have any information about Zygopetalum Trozy Blue? I'm assuming it's the same care as other zygos, so I'm not too worried about that. I'm just trying to learn about what species have gone in to make the orchids that I have as it's so fascinating!
