The Flora of St Helena is particularly diverse, with hundreds of endangered endemic species. In recent years there has been a program to conserve and replant the great forest on the island which was destroyed over the years. The Millennium Forest project has been successful and the forest is expanding rapidly. Read more on The Millennium Forest on the St Helena National Trust website.
St Helena harbours at least 45 species of plants unknown anywhere else in the world.
Today there are three major vegetation zones: the tree-fern thicket of the highest parts of the central ridge (central peaks). Of these, only the tree-fern thicket is a natural vegetation type. The middle elevations were formerly covered with native woodland of gumwoods (Commidendrum – St Helena’s national tree) and other trees, now largely destroyed. The barren “Crown wastes” were formerly covered with native scrub, of which a major component was probably St Helena ebony (Trochetiopsis ebenus and Trochetiopsis melanoxylon).
As well as the intrigue of endemic flora, St Helena hosts many other beautiful, exotic plants. The arum lilly (St. Helena’s national flower) is grown naturally in the wild and can be found near the banks of roadsides of the Sandy Bay Ridges, or Casons and Bluehill areas.
