The Nature of Plants: An Introduction to How Plants Work

Plant biology professor Huegel addresses this unassuming but superbly well-explained primer to the modest goal of educating gardeners in scientific fundamentals, “so that more gardens thrive and fewer plants die.” However, an active horticultural practice isn’t required for enjoyment. Huegel provides the basic facts of plant biology, starting with their evolution from ocean-based algae about 500 million years ago, and how the development of a simple vascular system made plant complexity possible. He walks readers through the mechanics of photosynthesis and the components of plant cells without jargon or assumptions of familiarity with those subjects. While Huegel does give out practical tips—such as that removing leaves and plant debris from lawns is a mistake, as doing so eliminates a valuable and natural source of fertilizer—the most eye-opening sections pertain to how plants communicate with each other as defense mechanisms, and to evidence that trees can send resources to trees directly related to them. This is an outstanding introduction that will serve avid gardeners well, and may also sway those who previously viewed plant life as inert and absent of interest. (Apr.)
