I grew Utricularia striatula while I was in Taiwan in peat. I used a plastic tub with a lid so the humidity was high. When I got back to the states, I put it in an identical setup but the plant melted. I don't know what I did wrong, since some Utricularia biloba I also brought back with me thrived in the same setup.
You can see how much the plant grew from when I first got it.
The plant in the last photo was flowering; unfortunately I did not get any pictures of the flower. ( #`Д´)
I would love to have another chance at growing this species.
