 The main flowering period is from May to June.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.
