The St John's-wort family, Hypericaceae contains some 700 species, most of which are tyropical. In Britain and Ireland the genus Hypericum cintains several species with yellow five-petalled flowers that grow in a wide range of habitats from marshes to dry sand dunes.
These thumbnail pictures have links to larger photographs and information about each of the species, their habitat needs and an identification guide.
We have used the Scientific names to identify species in this table, but all of wildflowers featured on this website can be arranged A to Z by either Scientific names, Common names or Botanical families via our Sortable Index Table, where we have also provided the facility to arrange flowers in order by dominant Colour.
