How long did it take for the potato to get from London to the south of France?

The journey of the potato from London to the south of France would depend on the method of transport used. Historically, if transported by horse-drawn carriage or boat, it could take several days to a couple of weeks. In modern times, with trucks or trains, the trip could be completed in under 24 hours. Thus, the time frame varies significantly based on the era and mode of transportation.
