How do you tell whats what? The ones that I see online use the same photos of dark red round maters. When we have bought them at roadside stands in La they looked more like Romas in shape and color.

I have absolutely no clue what kind I'm getting in the seed packet that is sold as "Creoles". But, they do make exactly the same tomato every year and across the years, so I'm thinking that they are true decendents of the LSU creoles. At this point it is all as clear as mud!
