I have a section of my garden that has been covered by a wooden board. The area underneath this wooden board was very damp and dark. There was this strange plant underneath the wooden board and I was wondering if anyone could identify it (click to enlarge):
To me, this looks like a bean sprout. But I don't know where it would have come from. I am in Canberra, Australia and the other plants in the garden are parsley, lettuce, broad beans, blueberries and spring onion.
