Can someone tell me why my water has not flowered. I purchased it two
years ago and it didn't flower so last year I re-potted it and there were
still no flowers.

Water lilies need a few hours of sun daily and dislike shade.
They hate water splashing on their leaves (from a waterfall or fountain).
They also dislike moving water unless it's very very slow.
They need to be at their optimum depth above the crown or thereabouts.

What variety have you got, some can be shy?
