St. John’s Wort Hypericum calycinum

Found this plant in the garden this morning. It is St. John's Wort and considered to have herbal qualities of various kinds. However, whenever I find it in my garden I always destroy it because when ingested by animals it can have detrimental effects on their health, even causing miscarriages in sheep. My Macro blip shows the full bloom, the extras show it before it has bloomed.
