About

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 halophytic plant is endemic to the western part of Sicily in small coastal habitats, and is a critically endangered species. 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. 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.

How to grow it

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.
