Lobularia maritima

1. Lobularia maritima (L.) Desv. (syn.: Alyssum maritimum (L.) Lam.) (Macaronesia, Medit., Arabia) – A regular escape from cultivation with uncertain naturalisation status in Belgium. First recorded in a sandy roadverge in 1870 in Ukkel (Brussel) and subsequently confirmed in 1874 (as naturalised) and 1920. Similar longtime presences are available for several coastal locations: De Panne (1937-1954), Knokke (1905-1939), Koksijde (abundant in 1956), Oostduinkerke (1945-1966), Oostende (1937), Sint-Idesbald (1959), etc. However, it is uncertain whether or not these records represent naturalised populations. Lobularia maritima is still frequently cultivated and probably still depends on repeated introductions. It surely sometimes persists for some time (mainly in climatologically favourable places like coastal dunes and urban habitats) but is probably nowhere genuinely naturalised.

Lobularia maritima usually grows in sunny, dry and disturbed, often rather nitrophilous places: worked-up road verges, dumps, ruderalised sea dunes, etc.
