Lonicera involucrata (Richardson) Banks ex Spreng. (incl. L. ledebourii Eschsch.) (N-Am.) – An exceptional escape from cultivation. Recorded in 2014 in Boekhoute (Assenede).
Lonicera involucrata is only rarely cultivated as an ornamental shrub in Belgium. Also elsewhere in Europe, it is only seldom seen in the wild, for instance in the British Isles (Stace 2010) and Germany (Meierott 2008).
It cannot be confused with any of the other Belgian representatives of the genus Lonicera on behalf of its black berries that are subtended by two very distinct, often purplish bracts.
