Door County, Wisconsin, is a place of tremendous scenic beauty and appeal with 250 miles of shoreline, 10 lighthouses, 5 state parks, and over a dozen county parks and conservation areas. Its unequaled number of wildflowers make it special enough to deserve its own field guide. Despite the fame of Door County and the great diversity of its flora, an adequate book to guide outdoor enthusiasts in identification of wildflowers has not existed until now. This easy-to-use guide contains nearly 400 watercolours, all painted from Door County specimens. Illustrations are grouped by flower colour to aid in recognition; within each group, flowers are arranged in taxonomic order. Labelled drawings of plant parts and a glossary are included. Even for the least experienced wildflower fan, it will serve as an easy and precise guide to the many flowers of Door County, while at the same time providing the wildflower aficionado with floral and descriptive details unavailable in other typical guides. Visitors and residents alike can better experience Door County's wonders and richness with this book in hand. Royalties go to the Door County Land Trust to further its mission of preserving, maintaining, and protecting the beauty, open space, and ecological integrity of Wisconsin's Unique Floral Preserve.
