Gardening in Miniature

As a boy, I did not embrace the hobby of making models. Yes, I had a train set, but no desire to create a world of villages, forests, and the like to surround the tracks. Instead, I wanted to be outside in the garden and working with full-sized plants.
This makes me feel a bit inadequate to review “Gardening in Miniature” by Seattleite Janit Calvo. However it turns out that at its heart, this is a gardening book, with sound design advice and cultural tips, just all at 1:12 (one inch = one foot) scale, or even smaller.
“Using the basic garden tenets of anchor point, balance, layers, texture, color, and focal point, you can plan your miniature garden with confidence,” the author states encouragingly. Step-by-step, fully planned projects provide lots of guidance for the beginner. I worried that plants would not stay to scale, and indeed they might not, but it’s easy to swap plants in and out.
I learned from this that while there is some overlap in principles and techniques between miniature gardening and bonsai, they are largely distinct pursuits. However, they can be combined by making a bonsai the centerpiece of your miniature garden. Will I take up miniature gardening? Probably not. But my eyes have been opened to a whole new—and quite small—world.

The Curious Gardener
Much fun is found in The Curious Gardener, published by Anna Pavord in 2010. This collection of writings from the British newspaper The Independent includes a serviceable gardening calendar for our region, but I’d especially check it out for the pure pleasure of essays written by a kindred, but at times contrary, gardening soul.
She begins with a tongue-in-cheek, astrological calendar of gardening signs (as a Pisces, it is good to know my intuition will help me “…recognize that a plant is in difficulty long before it is past saving”). Later she judges potential lovers by the choice of flowers they give on Valentine’s Day.
This same article brings out her political and environmental side, as she laments the ecological disaster caused by the huge business of producing cut flower roses in South America during the northern hemisphere winter.
An added bonus are the wood engravings by Howard Phipps, carved on the end grain of a block of very hard boxwood, using a technique that reached its pinnacle in the mid-19th century. It’s appropriate that the artist used a hand press from 1862 for the final images.

Environmental Horticulture: Science and Management of Green Landcapes

The subject of Environmental Horticulture, a new book in the Miller Library by Ross Cameron and James Hitchmough, is best described by the book’s subtitle: “Science and Management of Green Landscapes.” The intended audience is broad, but I would recommend it for professionals managing large landscapes used for almost any purpose, and for students researching landscape management principles.
This book covers many topics, beginning with the value of green spaces for human well-being and biodiversity. Many types of plantings are considered, ranging from trees and shrubs to bedding plants, and including formal settings and semi-natural grasslands. Even plantings as diverse as lawns or sports turf and green roofs or rain gardens are studied with the same depth of research as other types.
The authors define Environmental Horticulture as “…the subset of horticulture that is concerned with the use and management of plants in public and semi-public environments.” They discuss how this term is nearly the equivalent of “urban horticulture” or “landscape horticulture” with the difference uses reflecting national preferences. “Urban horticulture,” for example, hasn’t caught on as a descriptor in Great Britain.
The authors are on the faculty of the Department of Landscape at the University of Sheffield in England. Although some of the terminology is distinctly British, much of the discussion is based on North American research. One of the most valuable assets of this book are the references, which include many American sources.
