New en- thusiasm for “natural” foods has heightened this interest. In addition, most food recipes can be accentuated with the proper use of culinary herbs. Although many herbs are used for medicinal or ornamental purpos- es, this publication deals mainly with culinary herbs used in cooking. Location Herbs may be grown in beds, in rock as borders, or as corner plantings. Some herbs are annuals, meaning that they grow from seeds and complete their life cycle in 1 year; others are perennials that return year after year. Annual herbs may be planted in annual flower gardens or in veg- etable gardens. Plant perennial herbs at the side of the where they will not interfere with next year’s preparation. Many establish a small herb garden near the home. Gen- erally, a 6- to 10-foot square or rectangular area is sufficient. Circular or free-form designs can also be used. Plant the tallest herbs to the back of the plot.
