The Perennial Centaury (Centarium scilloides), which flowers in June, was thought to have only one native habitat in the UK – Newport Dunes. It has recently also been seen in Cornwall but it remains an exciting find.
It grows on the Atlantic coasts of Portugal, Spain and France but it is a rarity in the UK. Its seeds can survive for a couple of weeks in sea water and that may account for its distribution to our Western coastal areas. The dunes at Newport have a richness of wild flowers. Tread carefully!
