I was just reminded that The Elder does not belong into the Caprifoliaceae family any longer but is now in the Adoxaceae family together with genus Viburnum which also used to be in the Caprifoliaceae!
Adoxacea is now family number 137 and Caprifoliaceae follows with number 138 in Stace.
But the Lonicera or Honeysuckle remains in the Caprifoliaceae or Honeysuckle family.
So this post is now going to be shorter than anticipated and I will just talk about our useful native members as well as a few ‘weedy’ non natives. Info with thanks from various websites given in the links.
