Dianthus barbatus
(Sweet William, Stinking Billy, noxious ragwort)

I wasn't allowed to use this as bedding when i worked at Inveraray Castle, but "...the English botanist John Gerard referred to Dianthus barbatus as "Sweete Williams" in his garden catalogue of 1596, 150 years before Culloden" (from wikipedia)
