I have a dwarf water lily in a very small (40gal) patio pond. There's a fence cover that blocks sunlight, and it's underneath a potted large esperansa tree. It get's probably 2-3hrs of direct sunlight lol. It grew a good amount of pads that were beautiful. The flowers didn't come though I'm sure partly because of the sun, but mostly the esperansa above it was dropping in leaves that had leafspot, which transfered to the lily pads really bad. Each pad had a lifespan of about 1 month
But! it's def possible and I think looked not bad for what I was working with haha.

(sorry for the nighttime pic, I work long hours and don't get to see the pond in the sun often)
And a couple months later when the leafspot started taking hold...
