Then one day I discovered this one on the greenhouse trellis, too big to pick as a summer squash I decided to let it grow and see what it might become.
Reading another blog I decided it is probably a spaghetti squash. Not something I planted as I'm not fond of the taste, so it must of sprouted out of the compost, but where it came from to begin with I don't have a clue. Even if it turns out to be something else, it will at least be some chicken food.
The roots are some where in the tangle of plants in the foreground and it has run all over the greenhouse and up onto the roof with the other squash. It's the plant with the biggest bright green leaves running up the middle. (click on the pic to see it bigger).
