You can treat yourself to aromatherapy simply by lingering among the scents of a garden that has been planted with perfumed annuals and perennials such as jasmine, geraniums or roses, with fragrant herbs such as basil, sage, and catnip, or a combination of both. Many native shrubs and trees, such as tea trees, lemon-scented gums, and scented grevilleas, emit delicious aromas at different times of year, and can be used for healing purposes as well. And many scented plants come in a range of aromas, so you can develop a garden rich in different scents with just a few kinds of plants, such as roses, geraniums or thyme.
