If it seems wet all or most of the time, I would look for more of an upland spot and not a low lying spot that looks to you like a flood plain. Not only because the plant will suffer having wet feet all the time either. Also consider these two important factors. First, if its on a flood plain then eventually it will flood during periods of excessive rains. When that happens, you will most likely loose everything. Second, planting in low lying wet type areas almost gaurentees that your buds will mold before they are finished. Best of luck wherever you decide to plant.
