This is what gardening is all about. I am this close to having ripe tomatoes. I have about forty tomato plants, of seven or eight different varieties. This particular plant seeded itself, presumably from a still-viable seed that came out of the compost heap. I replanted the seedling in the garden. I suspect that my house’s previous owner was in the habit of throwing bird-spoiled tomatoes against the back fence, where a few of the seeds grew again.
