About

Solanum cheesmaniae is one of two main species of wild tomatoes found on the Galápagos Islands. This species is the one most commonly called the Galapagos tomato. It is a wild tomato that evolved on the Galapagos Islands.

It often gets confused with the other native species, Solanum galapagense, which is similar but slightly different having more bushy smelly foliage and having smaller hairier orange fruits. It also gets confused with natural [Domestic tomato x S. cheesmaniae] hybrids and [Solanum pimpinellifolium x (S. cheesmaniae or S. galapagense)] hybrids because of introduction of domestic tomatoes to the Galapagos Islands, and the presence of Solanum pimpinellifolium on the islands and natural hybridization occurring between them.

Where it grows

The species occurs on the islands of Galapagos, 500 miles west of Ecuador. They grow in extremely wet, rocky areas from sea level to up to several hundred feet. The flowers and fruits appear consistently throughout the year, but there is a noticeable increase in flowering between September and October.
