My U. alpina had made some rather impressive tubers:
..... and here's a bunch when they stay in the pot ... like marbles ...
I seem to have a hard time with orchioides Utricularia. I even managed to kill U. alpina.
If you shake a rain stick, you get rain. I need a hamata stick.
Wow! I thought the tubers in the first picture were stolons until you showed the second picture. Those bladders are really small. It's interesting how the lighting makes everything look green in the first picture. I thought that the plant was actually like that at first.
Wiki article explains, terrestrial utrics usually have very small bladders for the type of prey they are likely to encounter. U. humboldtii, which like to live in bromeliads, has some of the largest bladders.
