2. Abies grandis (Dougl. ex D. Don) Lindl. (N-Am.) – Sometimes cultivated as an ornamental or for timber production. Very rarely self-sown but possibly overlooked or merely neglected. Locally recorded in relative abundance in mixed wood in Torhout (Groenhovebos) since 2009, in the vicinity of parental trees. Saplings apparently easily grow tall (most ca. 200-300 cm tall in spring 2009). In 2010 also recorded in marshy woodland near Heverlee (Mollendaalbos-Meerdaalwoud).
Abies grandis is considered to be an invasive species in Great Britain (Richardson & Rejmánek 2004).
