I planted about 11 different tomatoes about 65 plants and I want to save seed from 3. They were planted in 3 rows next to each other about 4 ft apart. I want to save the seed because I got plants at the spring fling and do not know the varieties. But I am concerned that they will be crossed with others. One was a green with yellow stripe (maybe a green zebra) a dark cherry (?black cherry) and a big funky looking paste oblong yellowish red (do not know) all were op heirlooms. Since they all came from the fling maybe some one can tell me the names.
