Day 294: Hypericum calycinum is a garden-variety St. John's Wort, literally! A cultivar designed as a bedding plant, this species takes well to almost any type of soil. There are many sub-species and hybrids, and I can't tell you the exact nomenclature for this one because I snitched the slip out of a parking-lot planting twenty years ago. It spreads quite freely, often sending runners under sidewalks to emerge on the opposite side. In fact, once established, it's difficult to eliminate should you desire to do so. The blossoms are approximately two inches in diameter as opposed to those of its wild cousins which are rather small by comparison.
