What kind of tomato is this?

[lisaweingarten]

I have tomatoes that have lots of ridges in them similar to a pumpkin but with much deeper grooves. I didn't plant them, they just came up. How can I tell what they are?[/img]

Looks like maybe you were trying to post a picture, but it didn't come through. Here's instructions on how to do it:

It seems complicated the first time through, but once you get used to it, it's really pretty easy.

A picture would be very helpful!

Did it look like this?

If so they are a group of tomatoes called "Ridged Tomatoes"
