        I have this species growing in a Sarr water tray outside. It's
completely submerged in water and grows like a weed. The main problem is
algae. However, even algal infestations, squirrels, and racoons, it still
does fine.

        I have found that most aquatic Utrics in the wild only bloom when
water levels have dropped and they're in semi-submergent conditions.
However, flowering may have more to do with the daylength hours and
temperature while the low water levels were just coincidental (during the
fall after the 'drought' season for most areas).

        Hope that helps.
