William Robinson and Gertrude Jekyll helped to popularise less formal gardens in their many books and magazine articles. Robinson's "The Wild Garden", published in 1870, contained in the first edition an essay on "The Garden of British Wild Flowers", which was eliminated from later editions. In his "The English Flower Garden", illustrated with cottage gardens from Somerset, Kent and Surrey, he remarked, "One lesson of these little gardens, that are so pretty, is that one can get good effects from simple materials." From the 1890s his lifelong friend Jekyll applied cottage garden principles to more structured designs in even quite large country houses. Her "Colour in the Flower Garden" (1908) is still in print today.
