Anyone know how variable lemon seeds are? I know that I asked an apple guy about apple seeds once and he told me not to bother with them unless I was patient and had massive amounts of space because 99/100 apples are basically inedible and that typically they only do clones with some apple breeders doing the serious work.
You could eat them, but they taste like ass. Lemons similar? The plants in the above post there look pretty uniform.
