They look like old cultured Heirloom tomatoes. Try removing seeds from them, drying them out and planting them next spring. That’s what makes them heirloom.

I am wondering how your batch got the red "stripes" when a green zebra tomato doesn't usually have them.

I don't know, although they are planted betwee 2 red ones.......I was surprised too. I am going to save seeds and see what happens next year.

That's probably what happened, some kind of cross pollination.

They look like Ananas Noirs rather than Green Zebras...

All I can go by is the tag from the pot when I bought it in the spring Green Zebra. Here is the tag. I think it may have cross polinated with the reds panted on both sides of it, to get the red centers.

If it cross pollinated, you wouldn't see the difference in this year's fruit, but next year from any seed. They're lovely, but they don't look like any green zebras I've ever seen.

Maybe it cross pollinated last year.
