Fifty plants that changed the course of history / written by Bill Laws.

"Plants are so ubiquitous, such a common feature of the world around us, that we rarely stop to consider the profound impact they have on our everyday lives. We give flowers on on special occasions, spend many dedicated hours nurturing gardens, use them for dyes and construction, and turn them into cosmetics and medicines. We are also entirely dependent on them for sustenance - even when we eat meat, the animals that provide it have been raised on plants. Fifty Plants that Changed the Course of History is a beautifully presented guide to the plants that have had the greatest impact on human civilization. Entries range from crops like rice and wheat that feed whole populations, to herbs and spices that are highly prized for their medicinal qualities. Weaving together strands of economic, political and agricultural history, each entry is a fascinating look at the most influential plants known to mankind."--Back cover.
