Might need to let it get more crowded maybe?
Congrats, Ron! I've had this colony for a few years, now, and I've yet to see it flower. What did you to bring success?
Hmmm - that's a tough one ...
I received the plug, assessed the size, split it into two pieces (one large and one small) and potted them up (one in a 2.5" pot and one in a 1.5" mini-sample cup). Both pots have stalks with flowers.
Bottom line - I have no clue why they flowered for me.
Maybe it is the specific clone? I received three different clones of U. nephrophylla and two of them grew very, very slowly. The 3rd grew fast from the moment it was potted and was blooming in a month or two.
So far, U. warburgii is the most stubborn, non-flowering weedy utric for me (ignoring U. tricolor - of course). I've had it for over a year and it grows really well but refuses to send up a stalk...
This looks like a great ground cover Utricularia...How long are the scapes?
The scapes are difficult to measure due to their undulations but one appears to be about 15" (38 cm) and the others a bit shorter (so far - they keep growing as they add flowers). The stalk itself is also
significantly thinner than a U. nephrophylla stalk.
I don't know if the penny does justice to the size of the leaves. They are very small. I was surprised as I was cropping the pic as I didn't realize there were that many leaves - they were not obvious when I was taking pics. Again - although not obvious from the pic, the majority of the leaves are darker than other utrics (at least to my eyes).
On a separate note - unrelated to U. welwitschii - it looks like I have flower stalks coming from both windowsill U. longifolia & U. praelonga. I also have two stalks coming from my
smallest pot of U. nelumbifolia (different clone from the one that flowered last year - in theory at least).
