    Made a surprise discovery this morning which just made my day (I know - doesn't take much ). I was taking a quick glance for new flowerstalks in one of my tanks when I noticed one - but rather than a new emerging one - it was long. In fact, when I opened the tank, it had gone up the side and across most of the middle. As luck would have it, it happened to find the exact center of the crosspiece in the middle of the 75 gal tank - so it stayed hidden from me (& thankfully, out of the lights). When I looked more closely, it wasn't a new stalk, the U. humboldtii stalk (on which I'd previously crushed the growth point), had resprouted. I've never seen this happen & I know it didn't even start growing for 2 -3 weeks after the incident. With this new stalk coming along, the following species have the potential to be flowering at the same time (& I'm still holding out some hope for a U. reniformis or alpina stalk to pop up):

    - U. humboldtii
    - U. quelchii
    - U. nephrophylla
    - U. nelumbifolia (two different clones)
    - U. asplundii (two or three different clones)
    - U. campbelliana
    - U. alpina stalk is now emerging (edited to add)
    Here's a pic of the stalk - I'm really glad I didn't just chop it off - LOL

    This happened to one of my G. hispidula stalks... it aborted, I snipped off the end, and it resprouted a week later.

    Interesting, I know this happens among orchids in the oncidium genera where the flower stalks may branch very wide if the tip is damaged

    My U. alpina x endresii grew a tuber! Does this mean it enjos it's current growing conditions or it just wanted to form a tuber?
    Please excuse the crappy quality, didn't feel like getting the better cameras out.

    I would say it is probably happy with its conditions.

    For the species that form tubers, I think it basically means the plant is alive. Often, the plants are producing tubers but below the media surface so they aren't normally visible. I haven't seen any tuber-forming species not produce tubers.

    This is probably a good question for those TF members who have a Hort education.

    I made a setup for my Orchidioides Utricularia today using a plastic tub and long-fibered sphagnum moss. My plants were getting dry pretty quickly growing on windowsills, and this setup has worked really well for my terrestrial utrics (using peat), so I figured I would give it a try. Yeah, my Orchidioides were growing in lower humidity than my terrestrials. It is just Utricularia asplundii and reniformis in there. I figured this would also save water since the top of the net pot my asplundii was in was drying out overnight. I also added a dozen or so strands of live sphagnum. I wish I had enough to cover the top with it. The asplundii broke into several parts while I was separating it from its original media but the reniformis largely stayed together.



    I liked this picture of the stolons of the two species touching each other. I didn't plant them that way on purpose; it just happened.



    Hopefully the plants will do better in the higher humidity and live sphagnum. I will post updates in this thread.

    I found this VCPS article detailing growing Utricularia nelumbifolia from seed as well as an elevation chart for Orchidioides Utricularia as well as a few other species. It is at the bottom of the page.

    Thought I'd post this here also, more info about this box is located here http://www.terraforums.com/forums/sh...growth-display

    Windowsill lighting, household humidity, household temps Utric humboldtii that has been growing in there for 1.5 years and is keeping up or out growing my more controlled terrarium ones.
