Perforate (Common) St. John’s Wort ‘Hypericum perforatum’

From £1.50

A shrub-like plant with clusters of golden yellow flowers.  Known as Perforate St John’s-wort, common Saint John’s wort and St John’s wort, the common name “St John’s wort” comes from its traditional flowering and harvesting on St John’s Day, 24 June.

It is a believed to be a medicinal herb with antidepressant activity, although high-quality clinical evidence for such effects is limited. St John’s wort will alter growth form and habit to promote survival. Summer rains are particularly effective in allowing the plant to grow vegetatively, following defoliation by insects or grazing. A Orange/Red dye can be made from the fresh or dried flowers of this plant.
