Lycesteria formosa

This shrub is one of the best for attracting Sylvia warblers. Also known as Himalayan honeysuckle or Pheasant bush. It has attractive flowers and most important warblers go mad for the berries when they are stocking up before migration. I planted several and they now seed themselves . This summer I have caught 26 Blackcap and 4 Garden warblers on the land behind my house, and I put it partly down to the presence of this shrub. I once caught 25 Blackcaps all coming to one plant in my garden over a two week period. So if you have influence over any land areas plant this shrub and look forward to more warblers next summer.
