Dianthus Barbatus, also known as Sweet William. This a rather common plant in gardens but I recently learned it's name after much time seeing it and not having a clue. Now you know it too ????????

"Most plant historians believe that the plant is named after William the Conqueror, the conqueror of Normandy, because the plants were said to grow, “aplenty in the hills of Normandy”. Some, however, feel that the plant was named in honor of William of Aquitaine – the Saint, and still other believe that the name was a tribute to William Shakespeare who seemed to have a high opinion of the plant as is reflected in this quote by him about the plant, “for decking gardens as well as personal adornment”. - harvesting-history.com
