 St. John's Wort is a vibrant, creeping semi-evergreen shrublet that is frequently planted as a groundcover.  The distinctly veined oblong foliage is deep green in full sun or lighter yellow-green with shade.  Large yellow flowers with bushy stamen cover the plant in summer. Best bloom in full sun and well-drained soils.  Heat and drought tolerant once established.

St. John's Wort has been revered as a mental health herb and topical pain agent. There is discussion on the Hypericum family having similar attributes. Add the flowers to a salad or blend lovely culinary oils and vinegars.*
