Dirr’s Trees and Shrubs for Warm Climates is a sister book to his Hardy Trees and Shrubs, this time focussing on woody plants that grow in “warm temperate” areas found in USDA Zone 7 to 11 (where winter temperatures do not fall below zero degrees Fahrenheit. This book shows the habit, fruit, flowers, bark, fall color and more for 400 species (and hundreds of cultivars). This book is based on Dirr’s 22 years of gardening in the red soils of Georgia and offers reflections on his success and failures.
Dirr’s often humorous comments liven up the text throughout. For "Blue Pyramid" smooth cypress, he writes, "'Blue Pyramid' appears similar to ‘Blue Ice’, and both, growing side by side in my Georgia trials, look like rockets on the launching pad."
