Since the start of spring, a particular weed has sprung up more than any other on my plot, so I decided to look up what it was. I think I have found the culprit, and it is oilseed rape.
I found it on this useful weed identification site, which I think is primarily intended for farmers, but there are pictures of the seedlings and the fully grown plants.
I also found some interesting stuff about rapeseed/oilseed rape on Wikipedia. First, that it might have come from seed being blown in (there are numerous fields of this stuff on commercial land nearby). Second, there is a genetically modified, "Roundup Ready" (weedkiller resistant) version commercially available. I don't know if British farmers are using it, but that might explain why I've got so much of the damn stuff, and not much else - my application of weedkiller last season was Roundup (Glyphosate). Purely speculation, but interesting, Moog thinks.
Moog thinks this might be the first GM crop on my allotment!
Dear Moog, if your allotment was previously farmland the rapeseeds may not have blown in, they may be burried in the soil. My back garden used to be a farmer's field. It took about six years before rapeseed plants stopped popping up in the flower beds.
