Cross pollinated fruit
My zucchini (new seed) cross pollinated with my sugar pumpkins (been saving seed for several years from each yearly crop). This year I have the freak looking pumpkins. Can they be eaten? Should I cook them as summer squash or leave them to see if they form a hard shell? Or should I pull out the entire crop now and clean up that part of the garden?
Your vegetables would certainly be edible.
I would clean up the plants and remove them from the garden if you don't want mystery plants again next year.
