I've got a few horses, which means I've got LOTS of manure. We pile it up over fall/winter, and then spread it over our field in spring/summer. I had a few smaller piles this year, and this plant was a volunteer in one of the manure piles. I told DH not to spread this pile, as I was curious to know what the plant was. I'm hoping pumpkin, and that's entirely likely since we have a huge pumpkin farm behind our 10 acres. Also, I do feed my chooks pumpkins, squash, and watermelon, and I suppose it's possible that they could have pooped out part of a seed....anyway - what are your thoughts? Here's a view of most of the plant - it's a large plant, the largest leaves maybe being a hair smaller around than a basketball (?), and they are lobed. The actual plant is probably....oh, maybe 12' from one end to the other: I tried to get a pic of one of the flowers opened, but none of them were open at the time I took pics - but, they are yellow: And - here is the veggie that is growing - there are a few, maybe 3 of these that I've found thus far - at the time of the pic, this one was maybe just shy of the size of a basketball: I'm REALLY hoping it's a pumpkin - I've tried to grow them a few times and have never been successful, but to say I have a green thumb would be an out & out lie. Thanks for the feedback!
