Flower strips, seed mixtures, and wild by design. We want to help bees and other vital pollinators, which are in decline all over the world. But which flowers are actually the best?
This question prompted botanists from the Natural History Museum of Denmark at the University of Copenhagen and botanists from the National Botanic Garden of Wales to conduct a scientific study of which flower mixtures attract the most pollinators.
“Much of our knowledge in this area is anecdotal. So, there was a need for a scientific approach, where we systematically test different flowers to be sure how we can best help pollinators, which are extremely important to our ecosystems,” says professor and botanist Natasha de Vere from the Natural History Museum of Denmark.
Yarrow, Garden cosmos, and cornflower are a treat
The researchers reviewed over 400 previous research articles on flowers and insects and investigated how much bees and hoverflies like the finished flower mixtures that are currently sold commercially.
Based on the study, the researchers developed two new seed mixtures, which they evaluated both on the number of insects that visited them and on their aesthetic appeal to humans.
“We can see that seed mixtures containing both non-native and native flowering plants establish themselves better in the soil, bloom for longer, and have more visits from pollinators. And they are also most attractive to the human eye,” says Natasha de Vere.
