Utricularia campbelliana--cultivation in moss

Nov 4, 2016
Providence, RI
I had an idea a while back, and I was wondering if it makes any sense and if anyone has tried anything like it.

Utricularia campbelliana seems to do best for many people when it's either mounted or in a pot with holes. However, I've seen a couple of pots where it sort of looks like there's a mound of moss sitting on top that the utricularia is growing into. I have some live non-sphagnum moss sitting around--it's been collected over time from a Drosera filiformis pot. Would it make sense to fill a pot with something to hold water and for drainage (sphagnum-perlite-bark, based on what I have lying around), and then to stack up a bunch of moss on top of it?

My reasoning is as follows. It seems like Utricularia campbelliana likes growing with a lot of air--that explains why it does well mounted and in pots with holes. It also usually grows in a layer of mosses in the wild, although I admit it doesn't have much choice in an environment as damp as a tepui's peak. And it may like to have a moisture gradient, since many people do well by mounting it on something porous and sticking one end of the mount in water. Finally, by growing it in non-sphagnum, I will be able to make sure that it isn't constantly wet.

I got the idea from here. While this person didn't purposefully grow the moss, there's no question the utricularia does well with it there; whether it has an effect is debatable.

What do you think? Does planting into a stack of moss make sense? If not, I'm thinking I'll use a pot with holes (i.e. a cup that I poke a whole bunch of holes into) and the substrate I listed above, and maybe put some of the moss on the top.
