Mystery Beans

I’m a bit puzzled by the random broad bean plants that are popping up in the woodland, in the borders and in pots of bulbs. I can only think that a squirrel has cached the beans at some point and failed to return for them, but I’m not sure where it would have got the beans from in the first place. Our bird food does not contain them and my bean seeds are stored in a sealed box until I sow them in pots in the greenhouse. As I didn’t make an autumn sowing of broad beans, I’m leaving them where they are to see if they flower and set pods, if they do, it will be the easiest crop ever.
