I do landscape design and landscape maintenance professionally, and this is the number one book I reach for when I have a question about conifers, or simply need some inspiration for how to use one in a garden. This book combines gorgeous pictures of the individual plants and of their use in the garden, with incredibly thorough text.
The first part of the book includes brief but interesting information about the benefits using conifers in the garden, how conifers grow, and the origins and naming of garden conifers. Then he moves on to discuss, in greater depth, the different attributes you find in a lot of the more interesting conifers, like the differences and beauty of their cones, buds and new growth, bark, foliage colors, and the interesting forms and sizes available, to help you know what to look for and help you appreciate the truly unique attributes of garden conifers.
Then he moves on to my favorite part and a large portion of the book, Using Conifers in the Garden. The entire book is filled with gorgeous color photos suggesting plants to use in combination with conifers of every type, but this section outdoes itself with the amazing color photographs of the author's giant estate and the small vignettes he puts together using grasses, heathers, rhodies, and flowering perennials to accent conifers. This is incredibly inspiring and shows the huge number of ways you can combine conifers with other plants.
The written portions are amazing in this and the other sections as well. He discusses the different ways to use conifers in a garden to achieve different goals, ways of pruning and caring for your conifers to get different effects (Bonsai and Japanese gardening is discussed), conifers as container plants, hedges, windbreaks and screens, petite conifers for small gardens, and conifers as ground covers.
Last of all, he includes a directory of more than 600 outstanding conifers, including color photos on every page. Bloom knows his conifers well, and gives accurate and time-tested information on growth rates, habits, pest issues or problems, conditions needed, etc. His favorites merit glowing descriptions and praise, and his favorites have often ended up my favorites too, once I have had a chance to grow them.
The writing is simple to understand and would be accessable to a beginning to intermediate gardener, yet is absolutely depthy enough for the professional, and is a resource that once you get ahold of, you will not want to give up. It is great as an encyclopedic reference on garden conifers, and great for inspiration, instruction, and design advice.
