One of the greatest challenges in creating a garden is to acquire new and unusual species, to grow and nuture rare and exotic plants that few will have ever seen. This guide shows gardeners how to collect such plants and integrate them into their own gardens or greenhouses in unique ways. Druse introduces 28 passionate gardeners who he classifies into four categories: the hunters, seeking out the new and the different; the missionaries, driven to save threatened plants by growing them in conservancy collections, the specialists who focus on a single category of plants or a particular habitat; and the aesthetes, who collect for the appearance and values in garden designs. The collectors share with their readers their different ideas and common passions.
