Chase Devil, Goatweed, St Joan’s Wort and Tipton’s weed.
Habitat and Growing Conditions:
St John’s Wort is native to Europe and Asia. In Australia, where it has been introduced, St john’s Wort is classed as a weed as it spreads easily. The plant can lay dormant for 20 years and when livestock feed on it causes a myriad of health issues including photosensitivity and heart problems. St John’s wort is a perennial, it grows erect, up to 90cm high and prefers light sandy soil and regular watering or at least 60cm of rain a year. Its roots will grow deep but if the soil is shallow they will grow laterally. I have had no problems identifying the herb when finding it in the wild because as the name suggests the little leaves of the plant look perforated when held up to the sun. These perforations are actually oil glands. Hypericum perforatum flowers appear in the second year and are a bright, golden-yellow with five petals that have very small black dots around the edge. The center of the flower has many yellow stamens that remind me of a sparkler. If you squeeze the flowers you will get a red stain on your hand due to the hypericin oil. Tiny, sticky fruit bulbs contain the seeds and due to this sticky medium, they are transported easily by birds and animals.
