My uncle did a lot of farming years ago with his brothers . They had cows and pigs as well as planting a lot of acreage with cotton, soybeans and corn.All of that was for business, but there was always a family vegetable garden. Most of the family gardens I saw usually had a few rows of flowers on the edge. I never asked about it but wondered exactly why they were planted-- seems a little sentimental to me. Maybe it was a female member of each family who put them there! Anyway they were always beautiful.
