''Calendula maritima'', known as the sea marigold and trailing calendula, is a very rare species from the family of Asteraceae. Some scientists regarded it as ''Calendula suffruticosa'' subspecies ''maritima''. This halophyte plant is endemic to the western part of Sicily in small coastal habitats, and is a critically endangered species. 〔(EOL overview: ''Calendula maritima'' ) . accessed 11.30.2011〕 As of 2012, this plant could still be found in only five small sites in East Sicily. The Province of Trapani has chosen the plant as its official symbol. The sea marigold occurs only on the Sicilian coast: on the island mainland between Marsala and the Monte Cofano; and on the two nearby islets Isola Grande dello Stagnone and Isola la Formica. 〔(EOL distribution and habitat: : ''Calendula maritima'' ) . accessed 11.30.2011〕 The most significant population is in a small 10-km2 (3.9-mi2) nature reserve area within the Riserva Naturale Saline di Trapani e Paceco. It is on the IUCN Red List of critically endangered plant species. 〔(IUCN )〕〔Bertrand de Montmollin, Wendy Strahm & IUCN/SSC Mediterranean Islands Plant Specialist Group.: ''The top 50 Mediterranean Island plants : wild plants at the brink of extinction, and what is needed to save them.'' 〕 ==Description== This perennial plant reaches a height between .
