Leaves are up to 10", but they're "melting", showing signs of too much fertilizer. I'm actually below the recommended levels, but my soil tends to be richer, my sun hotter, and my water has fish, so I need to be careful. I added a bubbler and EE to help take up nutrients and keep the water healthy. There's actually one healthy leaf under the water in this picture, which I repositioned before and after it. The top leaf is the most recent, and looks much better than the bottom left leaf that came before it. If I can get two healthy new leaves, this plant will head to a display pond. Unfortunately, plans changed, and I no longer have the pond it was originally intended for, but I'll work something out.
