I can confirm this fact. I have U. gibba in an old aquarium in my heated
greenhouse. Each winter the aquarium is allowed to get almost bone dry.
The Utric also dries to form a green mat with the algae it grows with.
Last year when my heater failed the temperature dropped to around minus
5 Celsius. Guess what? The Utric is growing this summer again. This is a
plant that seems to thrive on abuse, which is probably why I'm able to
grow it!
