I have lined a plastic net pot with dried NZ Sphagnum moss and used a mix of peat/cypress mulch/dried sphagnum/peat chunks inside that, so it's a free draining mix. I was going to water germinate the U. reniformis seeds and then transfer them to the aforementioned mix, but now I'm really not sure if it is correct or not.
****** Update time ******
Last year I repotted many/most of my large utrics into netpots. As I suspected, I now have a love / hate relationship with them. Every plant that I stick in one (w/ live LFS) does better than previously and some are growing massively better.
Here's a plant that is enjoying the new neighborhood (suspected of being U. alpina x humboldtii):
.... but here's the rub - how the heck do you keep something like this away from the neighbors?
Here's a full pic:
In Jan, I mounted my U. jamesoniana on a treefern slab. It grew well for a while, then stopped and did noting for several months. When it looked like it was going to lose it's final remaining green leaf, it woke up and took off...
In May, I posted a quick preview pic of one of my U. asplundii flowers. They have been flowering non-stop since then and more open every day. I've done several pollination sessions and have offered seed over here. In that post, I also mentioned that the two plants I'm growing have shown consistently different flowers (with U. nelumbifolia for comparison):
Here is a pic of the more vigorous plant growing in pure live LFS (it has the shorter lobes and lighter center section):
Close-up of a shorter lobe flower:
.... and a longer lobe one (plant in a mixed media):
Virtually all of the flowers on the plant with the darker flowers had long lobes that didn't unfurl evenly.
.... another short lobe flower:
... and another long lobe one:
... and views of flowers on the stems:
As you can see from the multiple pics, there are additional differences between the flowers (beyond what I've mentioned).
Here are a few U. nelumbifolia flower pics - the 1st pic was already posted in the macro pic thread:
This one was taken at the same time but didn't make the original cut (not the same flower as previous pic):
.... and a friend that found a warm spot under my new bank of T-5 lights:
Did some long overdue maintenance in the utric tanks this weekend and finally took the U. quelchii pot out for a haircut & pic.
Here's the plant back in January:
.... and this past weekend:
On an unrelated note, my U. alpina 'Pittier Moon' is sending up a stalk now - in the hottest part of the summer - I hope it makes it - and I hope the others take note & get jealous ...
A few more unrelated notes / observations:
- harvested seed from crosses:
---U. nelumbifolia x U. asplundii (shipped spares out already)
---U. nephrophylla x U. nelumbifolia (only got a few - although more than last year)
---previously pollinated 2 U. nephrophylla flowers w/ U. asplundii pollen (u. nephrophylla x U. asplundii) -- neither pod had any seeds in it. What's up with that?
---previously pollinated a U. asplundii flower w/ U. longifolia pollen - I was quite shocked to see the pod has swollen as large as others. Will provide update if I get any seeds. (the 1st U. asplundii pollinations should be ready for harvest in the next week or so...)
---none of the U. praelonga x U. longifolia crosses (or reverse) produced seed (section foliosa)
---none of the selfed U. praelonga pollinations produced any seed either ...
Wow!! Thats a happy Utric.
Guess the net pots are working well for you. Now I just need to get one of those roots to find its way into a pot with my name on it .
I also don't know whether I have Orchidioides 'dry season' identification down yet (along w/ concomitant watering). Thankfully several species have been forgiving with my 'errors'.
