St John’s wort has been used to cure many ailments for hundreds of years. ‘Wort’ is an Anglo-Saxon word meaning a medicinal herb. The name St John’s wort came about because it was used by the nights of the Order of St John to heal the deep wounds sustained during the battles of the Crusades.


St John’s wort, hypericum perforatum, is an attractive medicinal herb which grows about —2 ft (30—6 I cm) high. Its upright, reddish stems are square and branched. The small thin leaves have veins radiating from the base of the leaf and growing thickly along the branches. Each leaf has numerous small perforations which can be clearly seen if a leaf is held up to the light. They are transparent oil glands, containing the same valuable oil as the flowers. This feature of the leaves is an easy way to distinguish the St John’s wort from other hypericums. The flowers, which bloom in June and July, are bright yellow star-shaped blossoms clustered together at the top of the stems. When in full flower the stamens stand up above the petals. The herb can be found growing along country lanes, on dry banks and waste land, in hedges and meadows.

St John’s wort is a neat growing herb to have in the garden and it can easily be grown from seed sown in May directly into its flowering position. Sow the seed in light rich soil in sun or semi-shade and, when large enough, thin the seedlings a handspan apart. In March it can be propagated by careful division of an established plant. St John’s wort has little fragrance when in flower, but when crushed the plant has an aromatic smell of balsam. The ripe seeds have a strong smell and the leaves and flowers have a bitter dry flavour.
