Tolumnias usually bloom once a year, mostly during winter, but can rebloom on the old spikes that remain green. A good reason to not cut off the spikes until they look like straw and only that part. If it is blooming on a new spike it is just a little confused about the weather. These like to get wet frequently and then dry quickly and should be grown in small clay pots.
Thanks for the information. I wasn't paying attention to see if it bloomed off an old spike, as I thought it was done for the year. I was thrilled to see it blooming! The clay pot it is in is real tiny and root bound. I don't know if I should repot later after blooming ends. Do they like to be root bound?
It has tons of space and the spikes are new. And yes, orchids like to be more root bound than other potted plants. Actually, it's not so much that they like to be root bound...they'd rather have their roots hanging free, but most orchids hate being in a pot full of medium that keeps the roots constantly wet. If Tolumnias rebloom they do it lower down the spike. It appears to be growing in charcoal, which is perfect. Make sure you water it several times a week but don't let the pot stand in any water. Did it come with a tag? Where did you get it? If you like these flowers then you might enjoy their larger relatives, Oncidiums.
It's a good thing you posted this thread. I see several of mine are starting to spike and need attention. One has three spikes but the tips of the spikes were jammed up against the greenhut wall.
This is a picture of it I took a week ago. So I guess I just leave it in the same little pot? It does look healthy now. I just want to keep it that way. I thought it was through blooming and decided to feed it a little african violet liquid food. Of course it just ran right through this charcoal. But a couple weeks or so later these little buds started! :)
Jairak is the name of a huge series of Tolumnia hybrid varieties with other names attached, marketed extensively by Better Gro and sold at Lowes. I have several. I might have that one or be able to identify it at another time. Check out mjsponies post http://davesgarden.com/community/forums/fp.php?pid=8993394 Dyzzy also has some further down the line.
