Habitat Information
Perforate St John's-wort is most characteristic of relatively unproductive wasteland on free draining calcareous soils but can be found on a range of habitats including meadows, open woodland, hedge banks and roadside verges. It has a deep tap root which allows it continue to grow late into summer. Regeneration occurs both by vegetative means (axillary shoots and lateral roots) and by seed.


Growing Information
A spring germinating seed best sown in autumn. Perforate St John's-wort can be added to a meadow mixture but, as it contains a toxin activated by bright sunlight, is best avoided if the meadow is to be grazed by stock.
