Hey LWB,
Mine is doing the same thing......must be "that time of the year" or something.
When I got it.....it had a looooong runner on it. From the base it must have been two feet long. Once I planted it, it sprouted two babies. And it looked like it wanted to flower but never did. I think it didn't because the whole runner was underwater.
I've since cut and planted the babies from that runner.
Now I've got another runner.......that is even longer than the first.
So far, i am keeping this one out of the water.
I, like you, am hoping this one will flower.
I'll keep ya posted.
