He does have one paragraph about tomatoes, but he also talks about Andean cacti like Browningia candelaris, "plants from places like cloud forests of Central America", Solanum pennellii, and "plants from (...) the Páramo of Ecuador".

My mother was able to grow tomatoes successfully in Pohnpei, which is at 3° latitude and never gets outside the temperature range of about 23°–32°. https://weather.com/es-GT/tiempo/10dias/l/cc8849a0250ec854cb.... They were pretty leggy though; she had a hard time keeping them alive.

> He's talking about growing tomatoes all the way through the article. Nothing but talking about how tomatoes grow

This is flat-out wrong. (And the comment you replied to is also wrong.)

He mentions tomatoes only 6 times in about 1500 words. These words appear half-way into the article, in only 2 of the roughly 16 paragraphs. Three of those instances are in direct reference or comparison to the wild ancestors of tomatoes.

While not specifying, the article also mentions high-altitude, tropical plants and cacti.
