better if it is grown as a sub-aquatic i.e. anchor it to a
substrate. Mine have produced masses of flowers this year and are
still flowering. Could be the same for the other species you
mentioned.
The only real aquatic I own is U.australis but while it is
growing profusely, it has not flowered for me yet.(BTW either has
U.pubescens)
