Those are the building blocks of landscape architect Piet Oudolf, leader of the "new perennial movement" that strives to use only perennial plants. A new book showcases his work.
ASLA's The Dirt blog reviews the Oudolf book:
"'Landscape in Landscapes' moves from small to large scale, covering 23 private and public gardens. Created with graphic designer Irma Boom, the book features full-color photos with unique insets showing the name, color, and proportion of various plants used within his landscapes, enabling readers to get a sense of these gardens in different dimensions. Mimimal yet informative text by garden writer Noel Kingsbury is there to just introduce the gardens. These photos can be enjoyed on their own."
