Thanks everyone!
Yeah it's on a ceder plank - typical oakhill fare. I didn't have time to remount it before the roots took hold, so I guess this is the way it'll be for a while!
Al,
Can't wait to see yours in situ in your terrarium
You're right - mine is greenish-cream as well. The first photos didn't capture that; probably due to lighting or something. Here's a shot that better captures the color:
Hi Calvin,
Well, it's no longer in the terrarium. I found the terrarium to difficult to maintain (for me). So I took the mount out and the aerangis is still on it along with some others and a couple of phals. It was very happy outside this summer and produced four spikes. One of them has blasted (the last and smallest).
Anyway, here she is.
