Gypsophila elegans Bieb. (W and SW-As.) – A very rare and ephemeral escape from cultivation. First collected in 1883 near a cemetery in Soumagne and in 1886 in a road verge near Tournai. In the 20th century also recorded at a cemetery in Verviers. At present sometimes seen as a casual garden escape or throw-out, for instance in 2010 at the former railway station of Trazegnies (Charleroi) and in 2013 on worked-up, sandy soil by the Albertkanaal in Grobbendonk.
Gypsophila elegans is also sometimes sown in wild flower seed mixtures.
