Anchusa procera

Anchusa procera Besser (syn.: A. officinalis subsp. procera (Besser) Lambinon) (SE Eur.) – A rare and usually ephemeral alien, possibly overlooked. Lawalrée (1953) provided an overview of early Belgian records. Well-documented from the Belgian-French border area near Adinkerke (Verloove 2002) where Anchusa procera seems to have been introduced on the occasion of the construction of the motorway Veurne-Calais in the 1990’s. It is locally well-established in sandy, ruderal road verges, waste land, ruderalized inland dunes,…

Although both species occur in the very same area in Belgium hybrids do not seem to occur. They are therefore kept apart in the present treatment (which is also in accordance with Euro+Med Plantbase;
