guavas are native to latin america, but are more popular in asia, for some reason. so, they probably should be in any grocery store that sells oranges, but you might need to check the asian aisle. the guava i bought was in the same section as the dragon fruit. it's quite weird - they picked up on something that we clearly ought to have been mass producing. they've been growing here, with rose hips, the whole time, just hidden in plain sight.

as such, there are varieties that have been manufactured to maximize the fruit content, but they may be harder to find here, where we're still buying the natural variety, and mostly for a market of asians that are no doubt as baffled as i am. that itself is unusual, and may be part of the reason they're so high in c; most of the fruit we eat has had the vitamins bred out in favour of bourgeois characteristics, like appearance and taste. but what it means is that we have the opportunity to modify this item responsibly, if we choose to, so that we don't lose the vitamins as we maximize the edible portions.

i have no idea what's really out there, here in windsor; i haven't looked that closely. i'll have to take a careful survey...
