Gardening with Shape, Line and Texture: A Plant Design Sourcebook by Linden Hawthorne

When designing a decorative garden, it can be quite helpful to think about the finished look as an artist might when painting. This book suggests plants and plant combinations selected with a painterly eye. These suggestions are divided into sections including horizontals and tiers, verticals and diagonals, clouds and transparents, and more. This is a book to spend some time with when in the design phase, or when something about your garden just isn't working and you need a new idea.
