[.ca] Dirr's Hardy Trees and Shrubs: An Illustrated Encyclopedia (ISBN 0881924040)

Take Dirr's with you when you go to buy trees:
This book is the standard for hardy trees and shrubs. It is a pictoral encyclopedia of trees that are hardy and should thrive in the northern half of the USA. This book is well-designed and organized--the author is obviously intelligent and understands the needs of landscapers. The book is alphabetical by genus and species. The text is succinct. Each species has at least one photograph of the plant in the landscape and, usually, close-ups. There are many useful tables at the back that list trees, shrubs, needle evergreens and vines, each by significant features, both design, for example height, flower color, etc., and cultural, for example requirements for moisture, shade, etc. Entries are indexed by both latin and common name. I live in the so-called lower midwest USA (SW Ohio), and I have found the recommendations to be reliable. My only significant variances have been in height, which is difficult to predict and highly variable depending on specific conditions. The midwest with its extremes of temperatures and humidity is challenging, and many plants may not achieve the expected height. But in any case, since I do not coddle plants, I would hesitate to plant anything not recommended by Dirr, thinking it would not be sufficiently hardy to survive in my location. I rely on this text. An important feature is Dirr's thoughtful inclusion of the location of origin of each species. If you favor native plants, this is important information and not always easy to locate. Used in combination with William Cullina's "Native Trees, Shrubs, and Vines", you should have all the information you need. My only complaint is the inclusion of introduced species found to be invasive and disruptive in some environments, such as Lonicera maackii (Amur Honeysuckle) and Berberis thunbergii (Japanese Barberry). I am not demanding "native only" landscaping, but I think it wise to cease using plants that cause damage to the native landscape, for example, Kudzu. Though these sorts of plants are still offerred in the nursery trade, I would hope that a renowned authority such as Michael Dirr, would help lead the move away from plants that, though popular, are actively disruptive in the US. Without "Dirr's Hardy Trees and Shrubs", tree selection would be significantly more difficult, and the chances of failure-to-thrive higher. The information is useful, the pictures are good quality and well reproduced, and the volume (hardback) sturdy and well bound. This is a great reference book for any public library's botanical/horticulture/garden section, as well as for those who need or want to know about selecting trees. It also makes a fine book for anyone simply interested in landscape trees or who values a beautiful, intelligently designed, and interesting book.

Thank God for Michael Dirr:
This is possibly the most useful book on trees for the non-specialist in existence (though any arborist or landscape designer worth their salt should, and probably does, have it). Here's why. Alone among books on trees, Dirr provides not only descriptions of the trees, but he offers landscaping assessments. And he is not faint of heart. If he doesn't like a tree, he'll tell you. For example, of the Poplar, he famously wrote, "I have never recommended a Poplar to anyone, at least while conscious." Of the Common Ninebark he comments, "an extremely adaptable plant, perhaps even to nuclear attacks, and once established, requires a bulldozer for removal." But it is when Dirr waxes lyrical about a tree that he loves that he achieves his apotheosis. He introduces one tree with this simple sentence: "I love this tree." He describes a beech forest as "one of the most awe inspiring sight in nature." The Silver Linden is the "Beauty Queen" among Lindens. Of the Maackii Amurensis he writes, "Unheralded and unknown, except in the gardens of the fortunate few." Based on THAT comment, and the pictures of this extraordinary tree, I set out to find one. It took some doing. Now I have an allee of them that was planted 5 years ago. Every time I stroll past them, I thank god for Michael Dirr. I also discovered the Metasequoia Glyptostroboides (Dawn Redwood) here. If anyone reading this can lay their hands on this tree and has room for it - GET IT. Among other extremely useful features are the tree lists included in the back. He has listed trees by size, fruit, flower - you name it. The index lists trees both by their botanical name and their common name. I can not begin to tell you how useful his evaluations are. I have a farm -- 150 acres. And bit by bit I am filling it with trees -- with Dirr's help. Without him I would be lost.

shallow content:
I was very disappointed in this book. Having read the reviews, I expect depth and content - instead I got a book with pretty pictures and shallow content. If you want a picture book with minimal comments on the trees, then this is for you. If you want a book for identifying trees and their characteristics, I recommend: Trees of the Northern United States and Canada, by John Laird Farrar.

Wonderful pictoral tree guide:
Dirr's color encylopedia of common landscape plants is simply beautiful. Not nearly as complete as his "Manual of Woody Landscape Plants", it is much more user friendly and definitely easier for the lay person or someone with a casual/new interest in horticulture to cope with. As stated before, he provides gorgeous pictures of many many landscape specimens while still providing pertinent botanical information (i.e. flowers, fall color, size, etc.). Unlike in his manual, his writing style is much more narrative than technical, and he includes more detailed descriptions, personal comments, and humor for each specimen. This is certainly not an exhaustive list of potential plantings, but it is of great value for searching out new plants (just look for the prettiest picture!) or trying to obtain a visual of what a plant that you've heard of or been reccomended (like in those ever-vague landscape plans we always see). Fun to read and easy to use, this is a great addition to any horticultural library.

Pretty and Useful:
Dirr has made an beautiful color encyclopedia of landscape-useful trees and shrubs. This book is more friendly to the amateur gardener than his previous gigantic reference book and has the added advantage of color photos. All of the expected plants are included as well as a large number of less common species and cultivars, but this book does not attempt to be an exhaustive reference like his earlier work. I am certain that a horticulturist would find a few glaring omissions, but I couldn't. The photos are the reason to buy the book, but the writing is also worth reading. Dirr conveys particulars about the plant as well as his opinions with humor and an intent to educate.
