Aquatic utricularia and dormancy?

[elgecko]

I currently grow 3 aquatic Utricularia.
The U. gibba I have, I read does not need any dormancy.
I also have Utricularia aurea and Utricularia inflata. I'm unable to find on the net if these plants require dormancy. Do they? If so what is the best way to do this?

The native ranges of the plants should provide clues but I'm thinking people who grow them would be able to comment based on personal experience. I too would be most interested in learning about this. Does anyone know?

aurea is a tropical plant. My U. inflata from FL doesn't go dormant

Hi Steve,

I keep mine up all winter, but if inflata is left outside it will sink to warmer waters and remain there through the winter. Once spring arrives it will rise back to the top.
