I had not heard of this term until i read this post on Gardenporn. It dawned on me that this was what we were trying to do in my garden- a garden planted with vegetables, herbs and edible flowers.
I was then off to my next task-Google the term and read up all about it. I came up on these 2 links on Brooklyn Botanical Garden, post 2 on bbg. I have quite a few of their books and like the simple way in which they explain things.
This is how our garden beds looked last year. A recap......these were re-purposed from the fence boards on the north side of our property
The tomatoes went in buckets (and in the background you can see the missing boards on the fence).
Granted that this didn't turn out to be a true Potager because it was all vegetables of one kind in one bed, and no ornamentals/ companion plants. The intent was there though and hopefully it gets implemented this year.
