None of my U. reniformis (large or small) are willing to flower in the basement under lights. However, sitting the small form on an east-facing windowsill has them flowering, so late last year I repotted a large form & stuck it in the window. Hopefully it will get the hint & produce some blooms in a year or so. Seems that seasonal variation (temps, photoperiod, etc) helps them a lot.Leaving them in the cold greenhouse all winter didn't do much harm did it
Beautiful flower! I wouldn't mind seeing a non-edited version of the photo if you feel like posting one. What's the annual temperature range in your greenhouse?
Fred,
Cool pic - thanks for sharing.
Is this the small form or U. reniformis or the renamed large form (U. cornigera)?

Considering I said I'd edited the background it it's not that difficult to notice
Yes - size can be very dependent on environmental factors. However, the leave shape can be a quite reliable indicator.All my U. reniformis, from several suppliers, have grown to the same size so I can't say if it's the small or large one. That inflorescence is 2ft high above the medium (and increasing) if that helps.
Yes, this is the article (odd that it didn't show up in my CPUK search). Interesting that the author & Fernando visited the same places, inspected the exact same plants & come to polar opposite conclusions.This may be the discussion Ron, http://www.cpukforum.com/forum/index.php?showtopic=35435. I must admit that Fernando's stance is persuasive.
A good Scottish legal judgment.
U. cornigera v U. reniformis case not proven.
I edited my post so the pics are above & below each other for everyone. From your description, it sounds like you have the large forms of U. reniformis (aka: U. cornigera - if you're a believer) as a single leaf doesn't take away the conclusion.edit: A little later. I checked the plants and I have 4 pots of the top leaf and one pot which has a single plant of the bottom leaf surrounded by masses of the top leaf ( I'm not sure which of your left or right is the top or the bottom). The latter pot was acquired as seedlings. Now that does get confusing.

How large are your leaves? My U. reniformis rarely exceed ~5cm diameter. Established pots of U. reniformis 'Big Sister' / larger form of U. reniformis / U. cornigera are almost always larger than 5cm - usually by a lot.
