Wilsonara growth habit
 

Well, I got this/these from Olympic Orchids, as mericlones. Actually the order was incorrect (I had ordered two different Wilsonaras, but the picker gave me two Tan Treasures instead). Anyway, this is the first time for me to get one of this group (yes, I know it's a tri-genus cross), and I assume habit resembles Miltonia, or does it?
I was surprised that they have basically doubled in height since early October (I keep saying that..but it did surprise me). And my expectation is/was that they would reach blooming size on a future (probably like third) pseudobulb. However, this single growth is now approaching the size of a mature miltonia (not quite..but getting there). Help me align my expectations, then if something happens earlier, I'll be surprised ;)

This becomes a large plant. Yours aren't blooming size yet.

Wow...ok, I probably need to hold a raffle in the spring and get rid of the extra plant. I want it..but space being at a premium, I don't need two, esp if they get large ;)
Thanks, like I said, I hadn't had one of these before and it's very hard to judge size in most photos. That makes sense, I couldn't believe how fast it seemed to be growing.

Mature pseudobulbs are easily 6" tall.

Geez, ok, it will have to live in the laundry room (on a table) and not on a windowsill.

Well, on one of the twins, the first growth has now matured into a PB and started the next growth, And with warmer weather, I may have to look to find a new home for my duplicate in a couple weeks.
