Vine Ripened Tomatoes

The seeds inside tomatoes are usually kept from sprouting because
tomatoes are acid. I have found that yellow greenhouse-grown
tomatoes must be less acid, because the seeds often sprout inside the
tomato. The skin gets all bumpy, and when I cut the tomato open,
there are lots of little plants. I haven't tried growing them.

I haven't noticed this happening with the red or orange greenhouse
tomatoes, or with the big ones. Just the smaller ones sold on the
vine.
