Incidentally, there is no relation to the word private. As far as I can tell Pliny the Elder first used the word to describe members of the genus Ligustrum. The particular privet shielding Ratz Manor from the hoi polloi produces small white flowers that smell revolting, but are clearly very attractive to bees. The whole shrub was vibrating with honey bees and bumblebees, as usual very high up in the canopy and constantly moving so my photographs aren’t very good.
Next to the privet is another white flowering shrub which is also popular with the bees, but I have not identified this one. Any ID’s would be gratefully received.
