Sometimes it’s fun to let things cross and see what you get. Friend of mine planted 3 or 4 varieties of squash (c. moschata) in ‘04. She saved seeds from each one and planted out all the F1 hybrids the next year. She’s done that every year since and is IIRC on F6 or so crosses by now LOL. Her kids like playing ‘identify the parent’ with the resulting squash. They’re all winter squashes but some of them are very interesting and pretty. She calls them her ‘box of chocolates’ squashes. She never knows exactly what she’ll get but they’re all going to be tasty! I’m planning on starting my own experiment with 4 varieties of c. moschata this year.
It’s interesting that they still produce, as hybrids are supposed to be sterile.
