If you are concerned about the decline in bees around the world and are planting a bee garden to provide pollen and nectar: stay away from fancy plants.
A team from Leeds University studied 24 gardens over two years and discovered that affluent gardens have less bees visiting them than working class gardens.This came as a surprise to them because they expected the higher plant diversity in affluent gardens to attract more bees.
Are bees turning up their noses at rich people's gardens in solidarity with working class humans? Not really. Beekeeper Ian Wallace explains in this Sky News video.
The takeaway from the Sky News article that the video accompanies is that you should eschew hybrid plants and new cultivars in your garden if you are trying to attract bees and create habitat for them. New introductions may contain less pollen and more petals that make foraging harder for the bees.
