Pretty nice looking flower. It seems relatively big too. Congratulation Lloyd.

Beautiful flower, especially given it's colour-tinged form!

Looking awesome Lloyd, sometime you'll have to let us know how your growing all of your orchid flowered Utrics.

My epiphytic utrics are growing mostly in one of my terrariums. The temp's are room temperature (21C+ to ?30C when the sun is shining. The humidity is high enough to keep the glass drippy. I leave the cover on when the humidity is low (winter) and open it a crack in the summer when the sun is shining. They get a variable amount of sun, through glass, a few hours a day, more in the winter when the sun is lower and the trees are bare. They grow in NZ LFS in a low dish (humboldtii), or in perforated plastic pots sitting in low dishes (endressii, nelumbifolia and reniformis). I let the water level vary about a cm or less. My longifolia sits in a plastic pot with an orchid type mix +LFS. My alpina used to be the same type of pot/medium as the longifolia-however for some reason, it died back (losing some cute, plump tubers!) and now is in LFS in a plastic cup humidity dome under LED's where it is recovering. My quelchii is in the latter conditions which it seems to like.

Lloyd - Those are gorgeous flowers! I have not yet been able to get this one to flower. Actually I've not been able to get any of my large utrics to flower.
They survive well. Grow many tubers. But the leaves mold. So, I was surprised to hear you are growing them in such humid stagnant conditions. I have mine in tanks too, with the lids cracked, and low humidity, circulating air outside the tank. Even with the top removed completely removed, I get white, powdery mold on the leaves. Do you not have this problem?

I don't do anything to avoid mould. The terrarium is 15 gal., not very big and no fans and usually closed and dripping with humidity. Plus they're just sitting in LFS in water. Some others are sitting in plastic cups one on top of the other with no air circulation sitting in moist LFS. Never any mould. I suspect the LFS has anti-fungal properties. Maybe the warm temperatures during the day keep the mould down? I do find mould is worst in cool conditions like in the garage with my dormant plants. That's really the only place I use anti-fungals. Maybe you could try raising the daytime temperatures?

My grow area is currently about 15, but I had the same problems this summer when the temperature got up to 26. My non-epiphyte species are growing in 2:1 LFS:peat in about 3cm of water, and the epiphyte species are in net pots on capillary matting growing in about equal parts LFS:fine orchid bark:perlite. I'll try an experiment with cuttings from a few species, and place them in warm, saturated air conditions and see what happens. That's one of the things I love about utrics, you really only have to inoculate the soil with them and you have a new plant. Makes for easy experimentation. If only my tuberous dews could propagate like that.
Thanks for the suggestions. I'd like to get these utrics to flower sometime. They are interesting enough on their own, but the flowers a spectacular. You seem to have a bit of skill in growing these plants.
