Marigolds are hardy plants that can withstand a lot of undesirable situations. This makes marigolds desirable for landscaping, new gardeners and children’s gardens. The petals of signet marigolds (Tagetes tenuifolia) are eatable, adding color to salads and dishes, as well as other species used for food coloring, dyes and perfumes. Farmers and gardeners have used marigolds as companion plants. The scent of the marigold is not liked by some pests, animals and even nematodes.
