海茴香名稱：Crithmum Maritimum/Criste Marine/Sea fennel/rock samphire
海茴香 Crithmum Maritimum、Criste Marine 通稱: Sea fennel在古代就為人所知但逐漸不被使用，被喻為法國國寶級植物。
海茴香是一種多年生傘狀花序植物。具有細條紋鋸齒狀的莖，可生長至20-30cm高。其氣味特徵與茴香的氣味相似，生長不易限量採收、面對嚴苛生長環境的特性，海茴香(Criste Marine) 更被喻為“21世紀最珍稀的保養成分”。
In the 19th century, Sea Fennel was being shipped in barrels filled with sea water from the South to London markets and was sold as Craest Marine.
In England, it was cultivated as an ornamental in gardens where it is easy to grow liking a light, rich soil. Obtaining seed commercially is now difficult, and in the United Kingdom the removal of wild plants is illegal under the Wildlife and Countryside Act 1981.
The reclaimed piece of land next to the UK ort of Dover is called Samphire Hoe which is named after rock samphire. The land was created from spoil from the building of the Channel Tunnel and rock samphire used to be harvested from the nearby cliffs.
