Any idea on how long it takes to get the flower to grow in the field to the east? I've had folks dragging fresh creek water to the field for what seems like a darn long time and I see no flowers. So does anyone know how long this takes? Thanks

It depends upon how many villagers you have working on it. If you have only a few, it will take many hours. I've finished it in less than an hour, but with many villagers and constant supervision to keep them at the task.
