The productive compost heap

Sometimes I wonder why I bother planting seeds when I see some of the produce that turns up in the compost heap without any help from me. The other day some pumpkin vines in the compost died off and revealed a huge Queensland Blue which had been growing underneath them. Mind you, I can't even remember the last time we had cooked up one of these pumpkins but have a vague recollection of a neighbour giving us one a couple of years ago. I never buy them as they are so huge and are hard to store with all the wildlife around the place.
