Mrs. Zeke has asked me to appeal to the collective brilliance of the Dope in order to unmystery a mystery squash that defied her googling.
It is a very dark green, hard fleshed winter squash that resembles an artillery shell (though not quite as tapered at the top.) It is about 12" long and weighs between 7 and 10 pounds (obviously this is just an estimate.)
The only thing we know for sure is that it is not a spaghetti squash nor is it a zucchini.
Any help would be appreciated as this is to form a goodly portion of tomorrow’s evening repast.
I don’t know why you didn’t see the hubbards; if you scroll down through the winter squash they are in alphabetical order and there are both grey and green ones. They may be too fat but they are definitely oblong-ish. Here’s a link to a picture of a hubbard that’s definitely oblong.
Last year, we grew some pumpkins in our yard. We saved the seeds from one of them and planted them again this year. What wound up growing from the seeds were several different squashes; one looked just like the pumpkins from the previous year, but the others were various shapes and colors, from ‘kinda zucchini-like’ to ‘yellowish, oblong, vaguely pumpkiny-smelling’. Apparently that’s what you get from planting ‘hybrid seeds’ rather than ‘heirloom seeds’…
It could easily be a cross if someone grew it from saved seed - cucurbits are often described as ‘promiscuous’ - that is, very readily pollinated by other species/varieties that may be growing nearby - or even if they were saved from a self-pollinated fruit of an F1 hybrid variety, they may not necessarily look like their parent.
