I used to pick shepherd's purse, but don't have it here. Besides that, there was the ever present dandelion (I eat them all the time, plus use the blossoms and roots), slick dock, salsify, purslane, daylily, wild mustard and cattail. I never did get to try cattail root, since it was so hard to harvest and never got around to trying the "cobs" in the spring. I probably listed the wild things where I used to live earlier in this thread, but probably missed a few, too.
