grannyticktock, if you get honey from a local beekeeper she will know where the hives were situated and what flowers were out at that time, if the hives were near fields of rape, for instance, that is a very distinctive honey, it varies a lot,in colour, smell, taste, how long it takes for it to go hard and viscosity , heather, clover too, borage or lime are all very distinctive honeys. You can watch the bees going in and out and see where they are going, and what colour pollen they bring back. Mostly unless it is from hives near fields of flowers, most honey is a mix. If anyone really wanted to know you can check under a microscope as pollen grains are different shapes. Honey bees can't gather nectar from all flowers, some flowers need bumble bees with their longer tongues. I don't think hives of bees disadvantage bumbles , it is the flora round the nest that does and you are less likely to have insecticide sprayed if there are honey bees around, as the farmer needs them for pollination
Many years a bee colony will produce more honey than it needs for winter, so harvesting that surplus is not harmful. Sometimes a hive produces no surplus so sugar syrup is a lifesaver there. What is wrong is removing what the bees need for the winter and replacing it with syrup, but a good beekeeper won't do that
