This is a beautiful little book on the fine details of backyard trees ... a great present for anyone who wants to know how to identify (and moreover, appreciate) a tree in almost any season. In Trees Up Close: The Beauty of Their Bark, Leaves, Flowers, and Seeds
(Timber Press, 2014), Nancy Ross Hugo and photographer Robert Llewellyn take you on a trip that you'll remember forever when you're outside -- in a park, rambling down your own street, or even in a botanical garden.
As they state in the introduction, "We want to convey that tree-viewing can be as exciting as bird-watching (perhaps even more exciting, if trees are your favorite wild beings) and that through intimate viewing, one's sense of trees as living, breathing organisms, as opposed to inanimatae objects, will be enhanced."
I can't imagine a gardener, a designer, any outdoorsy type who wouldn't want to have this book.
You don't have to live in the Midwest to find this book useful, as most of the trees that are profiled by author Scott A. Zanon will also be found in many neighborhoods throughout the Mid-Atlantic, the Northeast, and even other parts of the country.
Landscaping with Trees in the Midwest: A Guide for Residential and Commercial Properties (Ohio University Press, 2014), focuses on 65 desirable trees, selected mainly for hardiness and ornamental characteristics. A lot of my favorite trees are profiled in this book, among them the striped and paperbark maples; red buckeye; common pawpaw (I have two in my yard); American hornbeam, Japanese katsura; Cornelian cheery and Littleleaf linden.
Each tree gets its own page, including characteristics (fruits, flowers, leaf color, growth rate, etc), disease and insect problems, culture, and recommended cultivars. Photos for each include habit, leaves, bark, fruits and flowers. It's a handy reference for all those trees you'll likely be using in your designs.
Finally, there's a very useful guide on espalier fruit trees written by Karl Pieber and Peter Modl. Espalier Fruit Trees For Wall, Hedge, and Pergola: Installation Shaping Care
(Schiffer Publishing, 2014) takes you through everything you need to know about planting, training, and pruning fruit trees into great espaliers for walls, trellises, pergolas, and yes -- even espalier-ing for hedging. Througout the book, there are lots of photos and easy-to-follow illustrations that explain exactly how to get the result you want. And moreover, there are a lot of espalier designs that I hadn't seen before, along with the usual fans, palmettes and the like.
