    Ok.. that means I really need to find my very first orchidiodes and try to prove again my climate is for them, well, since we have like 8 species around I really would like to try and grow them, but have never found them for sale anywhere.
    Have you guys done tissue culture with them? if I get some I would definitely want to try it!

    I wouldn't call that a "nice" thing. I thought you misplaced the quotation marks. And is that longifolia?

    Several Euro shops have them in TC & ship internationally (although I'm completely unknowing about regulations for CR)

    I suspect that it would be quite easy, especially when compared to Neps & others. However, once you've got a healthy, mature plant, propagation is easy. So, unless sterile cultures are needed (or super hi-volume production), why bother?

    Once you've gone through the effort to rid a sizeable collection of an invasive**, my statements make more sense. You'll notice in various threads over the years, it's generally people who are just starting out (or with smaller collections) who ignore the admonishments of more veteran growers to "kill them while you can". Imo, the larger Orchidioides hit the sweet spot - healthy robust growth when given the right conditions but also reasonably easy to control.

    No, that's U. alpina - one of the most-forgiving species in section Orchidioides.

    ** even now, the U. quelchii that I mentioned in another post--- it's completely impossible to rid that pot of the U. nephrophylla*** that it came with. I cannot even make a division without contamination - so I'm being forced to start over from small root cuttings. I've got a flowering-sized, very healthy plant (& rare clone) that I've got to get rid of without even getting to keep any of the nice-sized divisions that could flower quickly.

    *** don't get me wrong about U. nephrophylla - I love the species - it's one of my favorites. After cultivating several clones, I have one that is very robust & free flowering that I keep upstairs (& use for pollination & seed production). The clone that is resident with the U. quelchii hasn't flowered in 2 years.
    All the best,

    As a last resort before you completely give up and toss it. I've had pretty bad luck growing nephrophylla completely submerged long term, were as quelchii will just grow out of the water. Might be worth a try.

    Knowing you though, both will just take off and flower for years .

    While it might not grow well under water, I suspect that it would take years (if ever) before it would die. Heck, Barry lists it as a lithophyte

    Yeah right - LOL. There's still several species & specific clones that haven't shared their flowers yet (ie: U. 'Jitka' & geminiloba) & most species do not bloom regularly (aka: not truly happy).

    Here's a few quick pics of the U. campbelliana flower stalks. I had to raise the treefern slab because the stalks come out at the bottom of the treefern & then droop. That's fine if they were in a tree somewhere - but not at the bottom of a small tank.

    Closeup showing the 5 ...


    Entire slab

    Let's hope it keeps progressing
    All the best,

    Yea, since Barry listed it as a litho I've tried many times to grow it that way and failed horribly every time. I suspect what he was describing was growing in an "epiphytic type raft" on rocks. Anytime I removed the "raft" the Utric died within a month or two. Even when I placed an establisted "raft" and let it grow in some, then started to remove the medium over time it would not take. I have given up on the idea of nephrophylla as a litho, and google searches in the past provided no help.

    Hopefully the camp will open soon, the more I see the growth habit of it the more I think I want one.

    A couple months ago I got in some new Utrics, U. reniformis is growing new traps well, suspended in water. The upper portion above the waterline/medium has put out a couple of leaves, they seem to discolor and die back slowly. The traps are much happier. Someone mentioned U. longilolia, mine is flowering and also has some aerial roots from the flower spike. I have not seem that before.

    Are you growing them completely submersed, aside from the parts that grow out of the water themselves? I would love to see some pictures! I might try it with some of my U. humboldtii if it seems like it will work.
