Plants That Attract Beneficial Insects
To encourage beneficial insects to populate your garden, provide them with their chosen foods and habitats. Many weeds -- including lamb's-quarters, nettle, knotweed, pigweed, and cocklebur -- as well as many cultivated annuals, perennials, and herbs are food sources for two of the most important orders of beneficials: wasps and flies. Most of these plants are members of two families, the Umbelliferae and the Compositae. Umbelliferae, such as anise, carrot, caraway, coriander, dill, fennel, and parsley, have many tiny flowers arranged in tight clusters. Compositae, such as black-eyed Susan, goldenrod, and strawflower, have central disc flowers surrounded by many ray petals. Mustard flowers attract lacewings (for aphids) and parasitic wasps (for cabbage caterpillars and coddling moths; they don't bother people or pets). Rows or interplantings of these plants can support a large beneficial insect population.
