I wish I had taken some pictures during the growing season because the wapatos appeared morphologically different from each other from one tank to another depending on the type of muck they grew in. The wapato in rocky mineral soil had leaves that were incredibly narrow, while a small planting I had in pure well rotted steer manure where incredibly wide and gigantic. They didn't even look like the same species let alone clones. That was pretty fun. At one point I added some chicken manure to the whiskey barrel where the narrow leaved wapatos where growing in the rocky mineral soil and within a week the leaves were growing large and wide. The chicken manure was actually pretty fresh and didn't seem to burn them at all. I guess they are just very nitrogen hungry plants.
I don't want to talk about the flavor or texture of wapato. If you search the internet you can find lots of references saying they taste like potatoes, chestnuts, a little nutty, etc. Maybe these things are a bit true, but at the end of the day wapato is not any of those foods and despite some similarity in flavor and texture it really has its own flavor and texture that can not be accurately envisioned if described as tasting like other foods which it is not. To me wapato tastes like a good source of palatable starchy calories. A very important part of a healthy varied diet.
