Researchers in Sussex University have used an experimental garden to put pollinator-friendly plants to the test.
They found that borage, lavender, marjoram and open-flower dahlias were very good for insects.
The wallflower was also very attractive to pollinators, while the least attractive flowering plant for insects was the geranium.
Marjoram was probably the best “all-rounder”, attracting honey bees, bumble bees, other bees, hover flies, and butterflies.
Borage was the best for honey bees and lavender and open-flowered dahlias were most attractive to bumblebees.
