Gardeners who seek an up-to-date, authoritative guide to the wealth of garden-worthy ferns available today will find none better than Sue Olsen. Drawing from four decades of experience as a fern specialist, Olsen leads the reader through every genus with horticultural merit, focusing primarily on the temperate species but also including tropical ones. In this comprehensive reference, Olsen presents succinct descriptions, habitat information, and cultural recommendations for more than 960 ferns, accompanied by 700 color photographs. Early chapters focus on ferns in history, as well as on cultivation, propagation, and structure. A series of appendices highlights qualities that will enable gardeners to further refine their choices, such as which species will tolerate dry shade, boggy conditions, strong sunlight, or other special conditions. Rounding out the volume are useful lists (with contact information) of places to see and purchase ferns.
