FOOD STUFF

Note, these ignore the elven lands.  Some of these may very well have originated in elven lands rather than the lands of men.  This is just at the very least the first places these crops were found/where they are found natively in the 4 provinces of men.  Many cyrodiilic crops are found throughout tamriel after repeated periods of empire and trade.

Many of the crops of High Rock also grow in northern coastal hammerfell, and many of the crops of Cyrod grow in southern coastal hammerfell.
