"Latah" tomatoes.
Pronounced "lay-tar". I got these from the Real Seed Co ., whose (false) assumption that they were Russian is understandable as they came from the Moscow campus of the University of Idaho. And they were selected for their tendency to ripen over the short growing season of a northern latitude. I am late in sowing them, but according to this site, planted out in late May, they were producing fruit a month later . We'll see. It appears from this 2010 article that the University of Idaho has been working on short season tomatoes since the '70s. Ariel Agenbroad tells us she "gets a kick out" of producing tomatoes with names like Latah, which is the county in which the campus is situated. And so, let's see how it copes with a Glasgow polytunnel's climate.
