Real Strawberries

I found a real strawberry today while I was mowing the yard. And by real I mean it was growing in the ground, and I didn't plant it. As soon as I saw the first one I started noticing them all over the place, poking their heads through the fence.

For comparison's sake, here's the Real Strawberry (on the left) and a strawberry I picked from the ones I planted.

I tried to find pictures of the different kinds of strawberries, but the best I could do was this from the Canadian Food Inspection Agency. Apparently there are over 600 varieties? What?
