My dad picked these up off someone's lawn at a house he was at. Anyone have any idea what type of seeds these are? They had an acorn-like but bird's nest (curly) looking crown on them, but I took them off before I brought them home.
Any tips on germinating them as well? They rattle around like there is something loose in there.
