I forgot to label 4 tomatoes in grow bags and I'm most curious what the hell these ones are.

only reason I know it's not is because I grew them last year and didn't grow them again this year.  this is my first year doing everything from seed and I didn't order any of those.  nothing against them I just wanted all new varieties.

Taking a shot in the dark here, Cherokee Purple? 
I planted these this year because I heard good things about them.

possibly.  I have 2 other atomic grape plants that aren't fruiting yet. so at least I know I own those seeds...

with that point at the end it looks like atomic grape to me
