Rhododendron and toxicity to honey via bees???
Hiya,
I want to plant a couple of said plants - but I keep finding articles on the web that say that honey made by bees visiting many (all?) of the subtypes of rhododendron end up with toxic (to humans) honey. Is this crap or is there any truth to it? Some neighbours keep bees and I don't want to do anything unecessarily adverse. TIA Tim |

Many years ago I used to keep bees, and I also grew lots of rhodies in the garden (see my reply to Sacha on her R. Yakushimanum query). My bees made lots of honey, typically 40 lbs per hive per season from two hives (we were out in the country, a lot of the honey came from brambles IIRC). I ate much of it, gave a lot away and also sold a lot of it locally. Nobody died. Even if rhodie nectar does give poisonous- to-humans honey, the proportion in any particular honey crop from a few rhodie plants nearby will be small to miniscule, so will have no detrimental effect. The fact that I got lots of honey means that the bees didn't suffer either. Thanks Chris - that's good to hear... |

A bit off topic, but something that has always intrigued me. How do you know where you bees get the honey? I know you can buy various types of honey (ie from specific plants) but is there any guarantee that it is really what it says on the jar? Eucalyptus honey is fairly unmistakable. I hate it BTW. I can usually tell one or two of the other New Forest honies too. |

When it says say "Heather Honey" its normally because the hives have been placed in an area where that is all that is in flower. So I assume the same applies for other sorts? "Heather" with a hint of gorse? |

Depends where the heather moor is, I am in the west and Gorse is as common as heather, but its not that hardy and you don't find gorse on all heather moorland. -- Charlie, Gardening in Cornwall Holders of National Collections of Clematis viticella and Lapageria rosea cvs http://www.roselandhouse.co.uk |

I can usually tell one or two of the other New Forest honies too. Sweet chestnut, linden (Tilia) and lavender honey all have very distinctive flavours. Rape honey is sold cheaper than the others here, I seem to recall it crystallises faster (or something like that) than the other kinds. -E -- Gardening in Lower Normandy |

Rape honey stays liquid in its original cells and is great for the bees to feed the larvae in spring, to increase the colony size rapidly. Once you take it out of its original cells it sets like white concrete in about 6 weeks and retains its cabbagy taste. No self respecting beekeeper would think of eating rape honey!
