Morphology
The phrase is compositionally built: 'wort' denotes a plant/herb, 'St John's' is a possessive proper name indicating the plant is associated with Saint John, and 'common' signals the usual/typical variety. A learner who knows these constituents can therefore infer that this is the common variety of a plant called St John's wort (even if specific botanical or medicinal details are not predictable).
Etymology
Common St John's wort may come from the plant's bright yellow flowers that often bloom around St John's Day, when people would pick it for special customs, and wort is an old word for 'plant' or 'herb'. That's why the name links the shrub to its long use as a healing 'plant' or simple 'medicine' for mood and wounds.
