Tomato Galapagos is a wild tomato from the Galapagos Islands and a separate species (Lycopersicon cheesmanii). It has small yellow, sometimes slightly oval fruits, which taste exceptionally sweet. It becomes bushy and is so robust that it thrives even in unfavorable locations and harsh climates. It is even said to be tolerant of a low salt content in the soil and is also highly resistant to the common tomato diseases.
