There is a good variety of tomato's that will grow in this area: Beefsteak, Brandywine, Super Italian Paste, Sungold,
Yellow Pear, Sweet 100 Hybrid, Better Boy, Lemon Boy, Celebrity, Roma, even Tomatilla's grow great in this region. There are more I'm sure, those are the ones off the top of my head! Hope this helps :)

Even here in Bucks Co. many don't put out their plants until after Memorial day and even though mine went out a couple of weeks before that,ours are the same size. I would expect you can pretty much grow any tomato you want to in Pittsburg if you wait until the 31st to put them out. I love Green Zebras,many which Janice recommended,plus Celebrity..heck,any of them. But you HAVE to grow Sungold. They're like candy.
