Linum grandiflorum Desf. (N-Afr.) – A very rare and ephemeral escape from cultivation. Probably first recorded in 1887 in Heist-op-den-Berg (foot of hedge). In 1952 also seen on a dump in Jamioulx (see also Lebeau 1954). In recent years more regularly seen but most often obviously sown in wild flower seed mixtures, except perhaps in Grobbendonk where Linum grandiflorum was seen in 2013 near a sand deposit at the Albertkanaal.
Linum grandiflorum is an annual and never seems to persist.
