Completely baffled...found this growing in our garden this spring. It was a newly created garden last year, and only squash we grew was zucchini (black zucchini I believe). The plant looks the same but the fruit is completely different!

Your zucchini may have crossed with another kind of squash, did any of the fruits rot on the ground and leave seeds?

I've had Zuchinni get that big when overlooked but I don't recall the stripes.

I'm sure some of the fruit must have found it way into the soil but where that plant was found was the cucumber patch last year. I've looked at about every type of squash/plant online and none of them really fit both the plant and fruit!!

Just cut open the largest of the fruit and discovered a soft flesh with large seeds developing. Took a bite and instantly my mouth was coated in slime...not appetizing at all!! Making me think that what we probably have is a cross pollinated hybrid between a summer squash (zucchini) and one of the neigbhors winter squashes (I believe they had spaghetti squash next door last year).

It probably won't fit any variety you can find as it is most likely some sort of accidental cross and not a named variety.

There you go, an accidental cross and not very tasty.
