|We recently recieved 2 types of plants from the same grower both with the scientific name hypericum calycinum on the tags. However one tag also said Rose of Sharon-Groundcover Perennial and the other said St. John's Wort-Herb. The plants look very similar, if not exactly the same. My question is...are the plants the same? And is this the same herb used in vitamins, also is it edible as a vitamin supplement. If used as a groundcover, how quickly does it spread and is it best suited in sun or shade?|
|Hypericum calycinum is the botanical name for a plant commonly called St. John's Wort (as are several other related but different Hypericums.) Here is some information about it going by the botanical name.
I am not sure what the assorted tags with common names or notes were meant to signify. In my experience it is better to go by the botanical name rather than common names. However, this is a somewhat spreading or creeping form so it could be used as a groundcover. I am not sure which herbal uses (if any) would be attributed to this plant in modern times -- you would need to consult with a professional herbalist.
