Lonicera tatarica L. (W and C-As.) – A rare but possibly increasing escape from cultivation. Recorded from several widely scattered locations, in Flanders as well as in Wallonia. Most records probably represent relics of cultivation (along railway tracks, wood margins near estates and parks,…) but apparently birdsown in bushes in coastal dunes, for instance near De Panne (mainly nature reserve Houtsaegherduinen) and Nieuwpoort. Locally well-established but probably not yet becoming naturalised.
This species and Lonicera morrowii are genetically very closely related and may well be conspecific (Nakaji & al. 2015).
