The C. maritima habitat outside the nature reserve is under serious threat of destruction due to urban development, such as expansion of the Marsala harbour. In addition, other threats and reasons for its rarity include air pollution in the nature reserve from the nearby salt-works and the competition of invasive species, such as the Hottentot fig 'ice plant' (Carpobrotus edulis), in all native locations. The exact number of the remaining native plants is currently unknown. ==Cultivation==

The sea marigold is cultivated as an ornamental plant, used as a flowering groundcover and container plant. Cultivars such as the yellow flowering 'Skyfire' and 'Summerlovers Skyfire Yellow', are commonly planted in gardens, parks, and street and highway median plantings; and in flower pots on patios and balconies. ==See also==
