Companion books -- but not for the novice since it is understood that the gardener here has been graduated far beyond the nursery class -- which devote themselves to a special field of horticulture. Herbs considers where and how the plants grow best, the families, annual or biennial, and the individuals in the roster from anise to wormwood. Instructions for drying and storing are followed by how to use them and recommended cook books. Fragrance is concerned with types of scent, groupings of the plants, all hardy, the surroundings, period of flowering, day and night aromas, annuals and perennials, house plants, perfume making and potpourri. For those who wish to go a-hobbying, these should provide much needed information.
