I Want to Grow a BIG Cattleya

[schwing]

The majority of the cattleyas I have are mini; flowers not over a couple inches across. I started those while I was growing under lights, but now that I've migrated to a small greenhouse, I would like to go to the other extreme.

Can anyone suggest any plants that would have really large flowers? Fragrant would be a nice bonus and green or blue would be icing on the cake, although color not as important to this splurge as size.

I usually do my shopping on eBay but with winter coming soon, my shopping season is coming close to an end. Also, I'm planning on going to the Chicagoland Show so if there is one I can look for there, that would make it convenient.

Thanks!
