Yeah, I was told that a lot of the common commercial stuff we get in seed packs are sterile hybrids, but with the influx of "heirloom" variety in the mix now they often grow as fertile plants and you can get multiple generations that will germinate in your garden. I don't even bother planting cherry tomatoes anymore, they just reseed themselves for me now, and sometimes sprout in the darnedest places! Like the gutters if I don't clear them often!?!?!?
I appreciate your input. It is something started from seed-I had thrown in pumpkin and honeydew, but this doesn't look like either of those. I guess I'll keep watching it and see what develops. Your hybrid squash thing sounds very interesting, I didn't know that could happen.
