Here are some funky "double" tomatoes and one really strange Sungold F2 - the little red one in front.
The Sungold that I chose for a winner in the recent taste test is actually an F2. I've been told that Sungold is a hybrid. My neighbor gave me a seedling last year and I saved seeds. I planted those (F2) seeds this year. I'm growing 2 plants and they have some obvious differences in leaf shape, productivity, fruit size, and fruit color. Sungold (the hybrid) produces loads of nice-sized orange cherry tomatoes with a 'bright' flavor. An example of the "better" Sungold F2 is the orange double in the photo, while the "not-so-good" one is the little red one in front. I plan on saving more seed from the really good one.
If you are interested in seed, please leave me a comment. I'll then email you and ask for a self-addressed, stamped envelope...or maybe a seed exchange.
