Sinopsis :
This book does not contain all the weeds, nor all the native plants that can be found on the prairies. However, it does include over 100 weeds that can be found in agricultural fields, pastures, rangeland, waste areas, gardens and roadsides.The primary classification of weeds in this book is by flower color, which match the colors seen on the outside of the pages. Within each color group, species are alphabetized by the common name of the weed. Maps showing the per cent of fields where the weed is found are presented for many of the weed species in this book.

Each weed discussed has charts on life cycle and habitat. The life cycle chart describes whether the weed will grow as an annual, biennial and so on. The habitat charts show how likely the weed is to be found growing in certain areas. The relative frequency appears in the number of brush strokes beside the area description. Three strokes beside the term “conventional tillage” means the weed occurs fairly frequently in these areas. The range of brush strokes goes from zero - meaning not a habitat for this weed - to three - meaning a very common habitat.
