I have never actually been able to keep this species for more than a few
months so the following information is very much second hand from how
other growers keep the plant.

I think live sphagnum is a good medium to start with for this
Utricularia. I have seen the plant growing in a peat soil but whenever
the plant produces stolons the new plants grow in the water tray almost
as an aquatic.

I don't think it is a difficult plant to flower once you have the
growing conditions right. This is the hard part! You need to grow the
plant as a semi-tropical though. I suggest a minimum temperature of 15C.
