I grew a couple of "S. Cheesmaniae" plants from seed I obtained from Trade Winds Fruits that were very productive. Sharing my photos and results with a staff member of TGRC UC Davis, it was determined that this was not the true S. Cheesmaniae, but rather a cross. Still, these plants continued to produce new tomatoes even in the triple digit heat, although the fruits had very few (if any) seeds in the heat.

I mention cold tolerant varieties of domesticated tomatoes because I have found that many of the so-called cold tolerant tomato varieties do quite well here in Tucson, and seem to survive our extreme heat (even though production stops in the heat).

Even though the Galapagos Islands don't appear to get as hot as Tucson (according to what I read), the two species of wild tomato (S. Cheesmaniae and S. Galapagense) are more drought tolerant and salt tolerant. Those would be benefits for tomato varieties here in Tucson.

I'm in the same boat as you with the wild/domestic thing, but my climate is the polar opposite of yours.


Either way, good luck!
