S. cheesmanii (Galapagos tomato)
A complete surprise to me this year was the Cheesmanii tomatoes from the Galapagos islands. For thousands of years these tomatoes have been being eaten and thereby selected by the tortoises of the islands and that is why it is a new species of yellow cherry tomatoes, very closely related to L. Pimpinellifolium (currant tomato). They are more saline resistant and require less soil than most other tomatoes and they are very sweet.
