This is maybe an aside to the point of the essay, but I've never quite understood why the serviceberry hasn't been domesticated as a crop. Varieties get bred as ornamentals, and those often produce volumes of berries, but you don't see them being sold as food. I've always had this sense that there could be a lot more food diversity today than there is. This might have some ecological advantages, to the extent some of those plants might be better adapted to certain niche conditions that might be difficult to breed other plants for.
