This showed up in my squash patch.

Squash, and a nice looking one at that. Did you plant any?

Yes, but I also threw in the guts of some I got from a pumpkin patch, where they could have crossed and this is the result. They are two different fruits in the pictures.

I planted peanut pumpkins, Long Island cheese pumpkins, delicata, luffa, Greek sweet red squash. I know it isn't any of those. We'll just have to wait and see!

I'll be interested to see it when it ripens.

it looks like a native mexican/latam/caribbean calabaza pumpkin: green with stripes.
there are many that you never see in stores, except for mexican in spanish/mex/latam markets. it is much sweeter then other pumpkins/squashes.
kabocha also has this coloration, but it is usually very squat.
here's a site with great pics! of many-many. perhaps, you can find yours?

That would be so cool! The mystery continues!

It looks a lot like the Hopi Vatnga. But it would be truly amazing to get that because I know the place where I got the other pumpkins did not plant that kind, and in didn't either. We may just have a new breed here!

i thought it would be a stretch too, but hey it's a great site! if i had a patch, i'd plant some! they are so-o pretty.
