HI Caroline. Welcome to the beekeeping section of ATP.
It's true the bees will seek areas that have lots of different plants over areas with just one crop. The reason they do is because like us humans they need a variety of nutrients that aren't availabe in all plants.
Monoculture crops don't provide everything a bee needs to be healthy. It would be like us eating just one food all the time.
Native plants are preferred but if they can't get enough from those they will visit other types of plants.
