Yellow out red in is an old storage tomato. Storage tomatoes where breed to have a long shelf life. Stored the right way these tomatoes can last way into late winter. How cool is that you can have fresh tomatoes on your pizza in the middle of a snow storm. The fruits are 2-3" and perfectly round 3oz globes. The vines are amazingly productive. I have been selecting this tomato for a few years now, when I first ran across it the skin was a true yellow, so I have been looking for the most yellow in my populations. So if you grow it and it comes out yellow let me know and I will trade a bunch of seeds with you.
