Centaurium littorale. Seaside centaury.

Life-form & Growth Form:  

Hemicryptophyte. Herbaceous biennial (including monocarpic perennials). Little/no vegetative spread.

Flowering period: 

July to September.


Coastal sandy habitats such as sand dunes. Uppermost levels of saltmarshes and calcareous, humus-rich terf close to the sea. Lowland. 


Habitat loss and fragmentation through development of amenity areas, caravan parks, private dwellings, agriculture and golf courses. Disturbance through high seasonal visitor footfall. Coastal squeeze due to agricultural improvement coupled with natural coastal erosion. Lack of light grazing in many areas owing to a reduction in the rabbit population due to Myxomatosis has resulted in rank vegetation and scrub encroaching on suitable habitat in many areas, including shading from the invasive non-native Sea-buckthorn Hippophae rhamnoides. Eutrophication as a result of cattle being over-wintered on sand dunes.
