Marigolds, for instance, repel insects with their fragrance above ground while releasing a repellent targeting pests below the soil.
Nasturtium flowers attract and trap aphids, while petunias repel aphids and a host of other insect pests.
Borage does double duty, deterring caterpillar varieties while attracting pollinators.
