This companion volume to the best-selling RHS Gardeners' Encyclopedia of Plants and Flowers describes well over 1,000 species, varieties, hybrids and cultivars. Herbs from all over the world are listed alphabetically by genus, and the plant portraits show many rarely seen herbs, alongside botanical information, symbols showing the parts used, and associations in history or legend. The book also contains a herb dictionary describing each herb's growth, harvest, culinary, medicinal and economic uses. Further sections cover the design of herb gardens, and herbs in the wild. A definitive reference work.
