The primrose is one of the oldest flowers in the English garden tradition — quiet, early, modest in the way of things that have been around long enough to know they do not need to compete. The Chartreuse version has taken this centuries-long reputation for gentle understatement and made it the color of something emphatically not interested in being overlooked. This is the most interesting character development in this entire collection. 3.25 inches across. One screw. No water. The development is irrevocable.
