Oaxacan

Also called Oaxacan Highland Gold, Oaxaca Highland, Highland Oaxaca, Oaxacan Gold, Oaxcan Gold

'Oaxacan' is a regional label for Mexican herb said to come from the highlands of Oaxaca, in southern Mexico. Cannabis reached Mexico in the Spanish colonial period, and by the 1960s and 1970s several states, Oaxaca, Guerrero and Michoacan among them, supplied the Mexican product imported into the United States. Dealers and writers of the era named it by place, though how accurate such names were is uncertain. A University of Mississippi survey collected one Oaxacan seed sample in 1973, and a veteran breeder's 2005 retrospective remembers 'Highland Oaxaca' as a 1970s import. Mexico's herbicide campaigns of the mid-1970s reportedly reduced supply. Today's 'Oaxacan Highland Gold' seed lines trade on that reputation, and any link to traditional Oaxacan populations is unverified.

Region
Highlands of Oaxaca, southern Mexico
How sure we are
Mostly lore. Oaxaca's place in Mexican exports is documented, but the named variety rests on breeders' recollections and seed-bank marketing.
Keep in mind
Seeds and flower sold as Oaxacan Highland Gold today are modern or re-created lines, and none can be assumed to match the plants imported in the 1970s.
