I grew Small Wonder from Territorial Seeds one year.http://www.territorialseed.com/product/1128/s
I had two plants. Just two.
I got 109 spaghetti squash.
I am not kidding. It was freakin hilarious. I don't know if it was the variety or my super organic garden soil, but I have never even heard of a squash yielding like that. I didn't know what the heck to do with them all! I think we kept about 30 or so, and I put the rest in the front yard in a wheelbarrow and a tub, wrote up a Freecycle post, and told people to come and get them.
They were really delicious, though. And a good, manageable size. Two squash was a perfect serving for our family of three. And they stored really well. So if you love spaghetti squash, have a cool place to store them, and want a lot, this is a great variety.
