Bees love nectar-filled herbs and researchers recommend planting the below to attract the most amount of pollinators.
Other herbs, such as coriander, fennel and dill, produce very small flowers that attract smaller bees. Fennel and dill also serve as food for black swallowtail caterpillars, and are easy to plant in your garden at home to help insects.
The study also suggests to use the leaves from the plants earlier for cooking or medicine purposes and to let the plants grow flowers to support the pollinators.
If you have the space, consider planting scent gardens made up wholly of herbs to help supply nutrients to the bees.
