Many crops from the Andes of South America grow well here in San Francisco, perhaps in spite of or because of our cool summers and foggy weather that resembles the montane tropics. We discuss the Inca civilization and their neighboring tribes – their culture, technology, livestock, infrastructure, geography, and so on, as it relates to the growing of plants. In the slides, we slip back and forth, juxtaposing plants and practices we know well around here with those up in Cusco or Baños or Lima and thereabouts.
