Hypericum calycinum

St. John's wort

Native to Southern Europe, southwestern Asia


Allan Armitage calls the species "one of the finest ground covers available" for good reason.  Excellent on slopes, in mass, or individually.  Drought, dry soil tolerant, it spreads quickly via underground stems to be a perfect erosion control.
