Ynghylch

Perforate st John's-wort can be found in open woods, along hedgerows and roadside verges, and on waste ground. Its bright yellow flowers appear from June to September and the blood-red juice that exudes from its stems has made it a focus for much myth and ritual. For instance, torchlight processions and gorse-burning were just some of the activities undertaken on Midsummer's Day, a pagan festival soon replaced by the Feast of St John the Baptist, hence the common name of this plant. It's also said that the red juice from its stem represents his bloody murder.

What to look for

Perforate st John's-wort can easily be identified as it appears to have many tiny 'holes' in its leaves; these are actually colourless glands that give off a 'foxy' smell. It has bright yellow, star-shaped flowers that are peppered with tiny black dots.
