Why did my zucchini plant grow a pumpkin?

I know it`s odd but we went outside to look at our zucchini plant and there was this huge orange…thing. we went inside and after a while cut it open and it looked like a pumpkin, smelled like a pumpkin, and it had what looked like pumpkin seeds! now i’m really confused XD

  • It wasn’t a zucchini plant. It’s not uncommon to buy a pack of squash seeds, any variety, and get one or two seeds that may look similar to the advertised variety on the label but are not the variety you expected at all. Sometimes “strangers” find their way into the sorting and packaging process.

    This is especially true if you accept seeds from gardening friends who save seeds.

    Or, did you toss pumpkin seeds into your compost and one seed made it through the winter.

  • Looks like you planted a pumpkin plant instead of zucchini. The seeds do look alike, and occasionally rogue seeds end up in the wrong packet. Or, you bought a mislabeled plant at the nursery.

    Another possibility – the zucchini was cross pollinated with a pumpkin somewhere in the neighborhood. This year at the fair, we had a kid bring in this weird looking zucchini that had gotten cross pollinated with hubbard squash… it does happen!

  • I have a similar problem, I planted pumpkin seeds from seeds I saved last year and now one of my pumpkin plants has two pumpkins and a short fat zucchini growing on the same plant. It must have been a hybrid pumpkin gone rogue!

  • Some kind of mix up during processing. I planted astilbes and got stargazer lilies. It happens.

  • Horrible Packing System. Period.
