Berberis darwinii Hook. (S-Am.) – A very rare escape from cultivation. Several young, birdsown plants were found on an old wall of the Groot Seminarie in Brugge since 2009. Similar records are available from the British Isles where Berberis darwinii appears to be a fairly frequent and established escape (Clement & Foster 1994).
