Herbs are very easy plants to grow and can even be grown indoors.
They require little care and space, have few insect and disease problems and require only moderate fertility levels. Thus, growing herbs has become continuing and satisfying hobby for many home gardeners. More common herbs, such as dill, basil and parsley are usually available from local seed dealers, and those that are less common may be purchased from companies specializing in herbs. Annuals usually grown from seed tend to grow, flower and produce seed during one season and then die. Biennial herbs grow for two seasons, flowering the second year only, and perennial herbs overwinter and flower each season.
