The Perennial Garden
This publication features an essay by Hugh Johnson, titled "The Herbaceous Border and Its Flowers", originally from The Principles of Gardening. Each spread represents a flower that can be found in the perennial garden. The left page simply defines the flower's height, blooming period, and whether it grows in full sun, partial shade, or full shade. The right page names the flower as well as the color(s) it comes in.
