...now make it flower

I'm don't know about alpina (I don't have that one yet). But I've have a fair amount of success with other utrics. The two things that I've found to work for me are (a) very high light and (b) fluctuating water-levels. Without high light, they don't seem to flower. However, the fluctuating water levels seem to trigger flowering once they have sufficient light. I've heard some people say that they have to be pot-bound to flower, but I've never found that to be an important factor.

Okay, I can accept that. So, what does work? I defer to your greater wisdom. Inquiring minds want to know.

good question.....all i know is those techniques dont work or i would have flowered them by now as what you describe is what i have been recommending for years for flowering terrestrials.......temp swings probably have alot to do with it, especially with ones like reniformis......except for nephrophylla ive not had much luck flowering the Iperua and Orchidioides section utrics, my best guess is because my temps are to stable with minimal variation from season to season.....
Hermes,
As Rattler notes here, not all utrics are created equal. Many of the weedy little guys are difficult to keep from flowering. Some of the others appear to be as much art as science. Here's a thread that will supply some info. I've only been growing a few of these guys for a short time so I'm very short on real world experience. People like Rattler & Pyro have years of experience so when they share their knowledge, I always try to listen up ...
Based on reading a number of threads on various forums, it seemed that photoperiod was important for U. longifolia. Using that info, I have one pot on an east-facing windowsill and 2 under lights where I've been adjusting the photoperiod. So far, 2 of the 3 are sending up stalks.
I think I have just gotten lucky with U. nelumbifolia as 2 of my plants are sending up 3 stalks (2 plants --> 3 stalks total - not 3 on each). Hopefully some day, I'll get to see some flowers on the others....

Well, I already knew that about utrics. However, I also realize that people tend to treat them more like low-light dews. As I said above I've never tended an alpine, so I offered what little I could. :-(
If rattler is willing to teach, I am eager to learn. I love utrics and am very eager to learn more about my favorite genus. I've read Taylor's monograph cover to cover and would like more info on the care of the more interesting utrics.
However, it appears as though I have rubbed him the wrong way.

You guys are funny! I have had U. livida, sandersonii white & blue, dichotoma, calcyfida, tricolor, subulata, warburgii, bisquamata, and a couple others flower. But for the life of me and all of done with photoperiod, temperature, and water fluctuations, I cannot get U. alpina or longifolia to do anything besides green foliage. If they weren't deemed somewhat valuable, I'd give them away!
