We grow it like our oncidiums but a little wetter all year. It can take warmer conditions than true zygopetalums, the summer temps can reach 100F in the shade here and has not effected it.

Ours is Tst. Melinda Marie ‘Blue Moon’

Other than color, they look very dissimilar to me.

Mmmm, I have both right next to each other. The li[ on his flower looks different from Tst. 'Blue Moon.' imho

That’s interesting! I’ve got another zygo and didn’t even think about making the connection. The other grows very different flowers. The type that come up right at the plant base.

Here’s the pseudos!

Zygonesia cyanea gives that gorgeous color, I think... and smaller flowers with wider petals. Hard to tell from your photo, but I suspect if you look at the very back of the lip, under the column, you'll see lines similar to what you see on the Zygo. (The part of the column that I can see just has that "look")

And, I have to say it looks exactly like the Zygoneisia linked above by Roberta!
They're growing in a somewhat medium-bright room, but further back from most of the light than others growing there. Sounds like the divided pair aren't getting enough water, if they like to stay moist.

They do.
