I have successfully grown pumpkins for the last few years for my
grandchildren, using the seed saved from a shop-bought pumpkin.
I used the same batch of seed for about 3 years.

Last year I saved the seed from one of mine and have nurtured 2
plants. However I now have 4 huge fat yellowy-orange marrows!
neither pumpkin, marrow or courgette!
Is it possible that last years pumpkins and gold-rush courgettes
crossed and I now have a new hybrid?
What next?

I think I have read somewhere that crosses between marrows/courgette
and pumpkin can produce poisonous fruit, so I would be very wary about
eating these until you have checked it out. One of the seed companies
may be able to advise.
