The U. reniformis has just started flowering, the first flower opening at the weekend. This first flower is just a smidgen larger than a £2 coin. the plants normally have a good display through to the end of June, I will update as more flowers come out..... if I remember.

Nice.
You seem to grow it in a greenhouse. Are you giving it full sun ?
I give a low light amount to my utric, otherwise, they seem to burn.
Alpina is blooming at the moment but reniformis is only sending leave after a Winter break.
 
Hi Shoggoths, Yes, it has always been out in the greenhouse and in full sun, or at least as much sun as the twinwall polycarb sheet lets through.
My plants sit out in the greenhouse all through the UK winter, with the first leaves appearing in April, and flower spikes developing in May.
Being from high altitude Brazilian forests, it likes cool nights and highish humidity. I control none of those factors, but do grow them in pure live Sphagnum and stand them in lagoons all year round, which would increase the local microclimate humidity.

Cheers

Hello Steve,

Thank you for the answer. Last year, the leaves wilted a lot when the light hours increased. I thought it was because it was receiving too much light, but just like you, since Spring arrived, new leaves have sprouted so I imagine the leaves wilted because Autumn was coming. I'm going to add a light tray and see what happens. I thought reniformis didn't like always sit in water, Ill give it a bit more water too.

This is how mine looks at the moment. There's always crazy stolons everywhere.

Hi Shoggoths

Here's some pictures of the foliage on mine, the leaves of which are about 4-6" tall, the first is the net pot, approx 12" diameter x 5-6" deep (pond plant basket), the other pictures are a plant in a 3" deep, cat litter tray, with no holes in it, which is also flowering, and has a VFT which is permanently wet/inundated (even in winter) with a trap trying to get above the reniformis foliage. The last is a picture of the flower in the cat litter tray.
You can see what I mean about the plants being being pot bound, which may encourage flowering.
As you can see they are in the greenhouse and get sun all the time, the net pot is in a lagoon and the cat litter tray gets filled every day, the main rhizomes are up to 1/2" diameter each.
So one plant is in an 'open' system and one is in a closed system, as far as water is concerned, but both are healthy and growing well. Nothing seems to phase it, although I fancy the one in the net pot looks better, although that is the older set up by some years (never been repotted) and that may account for it. The plant(s) in the tray are siblings from the plant that were cut out of the lagoon, from escaped rhizomes that got out the net pot.

The flower in the thread above is a bit of an anomaly, I've never had a four vertical stripe flower before, and some with some perfunctory Goggling I cant find one on line with four stripes either, I'll let you know how the next one turns out.

Cheers
Steve
