I had to share this with you folks. I was truelly pissin maself when I found it. I have been collecting old roots, old vegetables, waste from the kitchen and general plant matter from my garden. This was for the start of my compost heap which I have yet to get a container for so was just keeping all the stuff in black bags. Well I am on my second bag which was lying on top of the first. I went out to throw some old shop lettuce that had gone limp in 10 minutes flat. I lifted the top bag up and low and behold this little bugger was growing out of the bag underneath. I think it was in some of the trim or popcorn that I made hash from. I threw all the waste into the compost bag. Either that or its come from all the old roots that are in there.
