Borage simply refers to the flower that the bees have used to make the honey. Sometimes we have a type of honey that is predominately from one crop, such as borage. This means we've moved our hives onto this crop so the bees can feed on it.  In the case of our other honeys, such as Summer, there is more of a mix of different flowers as the hives haven't been placed on one particular crop and the bees have visited many different nectar sources in the area.
