Bees love certain flowers! They probably have a different taste. Like imagine, you are waking up as a bee and you go to pick your breakfast flower! It's like picking from a huge selection of cereal everyday! Am I the only one who thinks like this?
idk about flavour, but i once read that they pick flowers depending on their colors, they prefer whites, purpled and blue flowers, always going for more light colors.
I cant remember where i read that tho, if i do find it ill add it here :)
