DOWNLOAD EBOOKThe European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 3 contains accounts of 47 families, including those formerly included in the Leguminosae (Mimosaceae, Caesalpiniaceae, Fabaceae) as well as the large and important Rosaceae. Also included are those families formerly covered by the name Saxifragaceae (Saxifragaceae in the strict sense, Penthoraceae, Grossulariaceae, Parnassiaceae, Hydrangeaceae and Escalloniaceae).
