They should have enough time to mature. I usually get some in late September or early October, and those might not have time, but even those grow large enough to use in their immature state - just use soon.
I just found something disgusting - where the early crop I got of butternut squash was curing, and I was ready to take the 12 of them to the basement, one had that sort of "wrinkled" look, I watch for all winter, and it when I went to pick it up, a finger went into it! I very carefully moved it into a tray, and moved it to my compost. It was one of those "Butterbush" type I tried these last two seasons, and won't grow again. Only one per plant, smaller, and none lasted very long, but this was the worst! I still have one of the Polaris from last season, on my counter, I have to use!
