I am growing seed which I took from a 5lb orange pumpkin that my grandson grew last year (which in turn was grown from seed taken the year before from a pumpkin bought from Tesco for Halloween). All 4 of the plants that I have growing are producing what look like marrows at the moment the largest is around 10" long, 6" round and weighs around 2lb. Could it be that the plants have reverted?

Last year they probably cross pollinated with some other cucurbit - marrow, courgette, squash, resulting in what you have growing.

They were next to the courgettes so I could well have a lot of courgette and cheese soup to make.

sounds like the pumpkin and courgette got intimate

Sounds as if halloween could be interesting

A lot of Pumpkins (the big orange ones sold for Halloween) are the same species as Courgette (Cucurbita Pepo) and will cross very easily.

Sounds a bit seedy to me

Funnily enough, this morning I was manually cross pollinating the male flowers from courgettes with a couple of female butternuts, to get them up and running. Squash do seem to take an age on my plot to get their act together. Plenty of stag and hen parties around and about, but little else.  Left to their own devices, it'll be August before any storks arrive.... very shy.
I've never been confident enough of the squash seed to actually save it and give them a go. It probably needs quarantine to get a good result next year, and that takes a lot of room and effort, or as DD would say, faff.

Seems like a good time to link to my first ever post on this forum 8 years ago!

I used the biggest one to make moussaka today instead of aubergine, it came out very well so I think a few will follow in its footsteps. Thanks for all the responses.
