No,the bottom layer is very coarse peat and the top is moss (not Sphagnum)Are you growing that on agar?
My U. campbelliana is growing like mad... subsurface! Fortunately I have it in a jar, so can still see it
Nice... I wish it was easier to trade plant material across continents.A while back, I crossed U. asplundii with U. jamesoniana (both directions) but only the seeds from the U. asplundii seed parent germinated.
I planted seedlings both in netpots (in live LFS) & one on treefern. The one on treefern flowered before the others:
Front

Ditto - but I think we'd really get the best end of that...Nice... I wish it was easier to trade plant material across continents.
Thanks - but based on some comments on CPUK, some feel it is not really a hybrid - just a selfing with natural variation. I expected that view before I posted. I'm not completely convinced either - but based on the info I have - I suspect it is a hybrid. As more experienced folks chime in with opinions and others make the same cross - we'll eventually find the truth. I also have several other siblings growing. On a separate note - I have a U. nephrophylla x U. reniformis cross sending up a flower stalk. Like the nephro x nelumbi cross - there should be no doubt to this cross as the seedlings are already larger than the seed parent.Spectacular hybrid Ron! Very beautiful plant.
Agree - lots of good info tucked in here.Been learning lots from this thread
No secrets and no definite approach that guarantees success. My best success has come from sowing seeds on wet LFS. If I have lots of seed, I'll often spread it around & try a few different media. I have many, many times when nothing germinates. I've not gotten any germinations when U. jamesoniana (mine) or U. campbelliana (Tobias) is the seed parent. The seeds are so small .... Tobias recommends sowing on moist sterile cotton pads - which I've tried without success. Most of the larger Orchidioides tend to germinate easily (when the seed is viable). Sometimes I've sown seeds & forget about them and later notice small seedlings poking up from the LFS.@Ron: you managed to germinate orchidoides seed? please share your techniques!
Ditto. I've tried on finely chopped LFS and cotton pads, with zero germination. Though, given the slow growth of even a mature U. campbelliana, it's hardly surprising that the seeds are challenging. They are like specks of dust... it's difficult to tell if they have even transferred to the growing medium.I've not gotten any germinations when [...] U. campbelliana (Tobias) is the seed parent.

The flower opened this past weekend but I figured I'd wait a bit for it to fully open & see if it changed. Today, I snapped a few quick shots just in case....Nice work Ron I can't wait to see what the other seedling looks like.
I've been quite resistant to keeping either campby or james on the wet side. However both have responded very well to add'l moisture. When I've started either on a slab, the 1st thing they do is send runners down to get their feet wet. Once they have a colony next to (or in) the water, they expand from there. Both have also sprouted multiple leaves under the water.I've found that the campy prefers the wetter end, though the runners in the second picture are from higher up.
Carl,
Your campby has amazing vigor. When you showed pics growing inside the little container (iirc), I figured it was an aberration - but even on the sponge, there are loads of little leaves shooting out everywhere! You don't fertilize do you?
