Floral Fidelity in Honey

Here’s an example of why I go out of my way not to mix honey from different hives.


The honey on the right was taken from one hive, and it tastes heathery. The honey on the left was taken from another hive, and it has a more earthy flavour. Both were harvested on the same day. The two hives are about 2 metres apart (7 feet), but the bees from each hive favoured different nectar sources, which resulted in slightly different honey from each hive.

The favouring of specific pollen and nectar sources is called floral fidelity. The bees find an abundant nectar source and they stick with it instead of wasting time jumping from one type of flower to another.

That’s why you’ll often see a flowering tree loaded down with honey bees while at the same time not a single bee goes anywhere near your beautiful Forget-Me-Nots. The results of floral fidelity are lost in most large beekeeping operations that have to blend all their honeys together. Not me.

November 22nd, 2016: I think it’s fair to say that honey bees (and all things in nature) are motivated by efficiency. It’s more efficient for a honey bee to learn how to get the nectar out of a single species of flower than multiple species of flowers.

A honey bee’s brain, while densely packed with about one million neurons, is a tiny little speck of a thing around 0.5mm thick, and that speck can only hold so much information. It has to erase the old information to make room for any new information that’s coming in — new information that slows everything down because the bee is essentially learning something new.

Judging from my observations:

1) A honey bee knows how to get to a specific location, the location of the flower. It leaves the hive entrance and literally makes a beeline towards the flower or the general location of the nectar source.

2) A honey bee knows how to extract nectar from the specific species of flower. The size and shape of each species of flower requires a different technique for holding onto the flower and reaching inside it to suck up the nectar (or collect pollen.)

3) A honey bee knows how to get back to the hive, specifically the hive entrance.

A change in any of those three greatly reduces the efficiency of the honey bee’s work. For instance, changing the location of the hive entrance by adding a rim beneath the inner cover (an inner cover with a top entrance) will move the top entrance up by only a few inches, but it’s enough to make most of the returning bees crawl all over the front of the hive looking for the entrance. Because the entrance is no longer in the exact spot it was before, each individual honey bee has to reprogram its little speck of a brain to learn the new location of the hive entrance. Sensing the disoriented bees, other foragers will often start scenting the location of the new hive entrance to save the returning, confused foragers from having to crawl blindly around the front of the hive looking for the entrance.

A change in the type of flower has a similar effect. The nectar isn’t located in exactly the same location on every species of flower. Flowers have evolved so that in order for the bees to get the nectar, they need to rub up against the pollen, so as to transfer pollen from one flower to the next. To the tiny speck of a honey bee’s brain, every flower is an entirely different puzzle they need to solve. And solving that puzzle slows down the bee. A new flower means the bee has to forget everything it knew about the old flower. That’s why the laws of efficiency compel the honey bee to stick to one type of flower, so all it has to do is repeat the same process over and over again, automatically and efficiently collecting nectar from a single species of flower all day long.

Hence, the magic of floral fidelity, and why bees will completely ignore one type of flower for another type of flower. (This is an extremely simplified explanation.) It also explains how varietal honeys are created, and why I don’t mix honey from different hives, or even different frames if I can help it. Too much is lost when everything is blended together.

  1. Hello Phillip and all!

    Thanks ever so much for this wayyy cool introduction to floral fidelity. Now there’s a good idea!

    I am a botanist and soil microbiologist in Placitas, New Mexico. This is in the northern foothills of the Sandia Mountains which tower over Albuquerqueque. I try to follow all our local pollinators, at least 25 species of pollinator insects and we reckon 200 + species over all, within 3 miles of here where I now sit. Of feral honey bee hives, I guesstimate we have 6 or so feral honeybee colonies based on the recent two swarms in the little village of Placitas. And over the past 20 years I have pruned the five largest orchards here, totaling 250 trees of ten species of commercial fruit.

    Expositions such as yours here quite simply blow my mind. You have given me so much to think about for our Placitas-based Natural History Museum at the Library. Keep up the good work…

    I’ll try to report back.

    When I was the Head Gardener at the Shangri-La Health Resort in Bonito Springs Florida 35 years ago, there was a lovely elder man who came there for the water fasting and raw foods. He talked of his honey collection and of trading honeys around the country. I remember that we agreed that the color of buckwheat honey can appear to be a perfect amber. Do you know of other folks collecting honeys of various floral fidelities?
