I found this site with an article about a centuries old chateau with a potager arranged by color. It sounds so pretty. And the rosey brick walls must be beautiful with the espaliered pear trees. I think I may have to try espaliering something.
I hope some of you will enjoy reading this, as well. There are some other interesting links at the end of the article. "Purple haze" the lavender trail at Provence will take your breath away!
