Hesperis Matronalis 'violet' has scented mauve flowers which look wonderful in a huge jug or vase & scent a room. Pick the flowers
...Pure scented white sweet rocket flowers that were a favourite of Marie Antionette. Hesperis matronalis or Dame's violet grow amazingly happily in sun or shade. I saw an incredible sight of both the violet & white form lining both banks of a river near Thirsk in Yorkshire, where Dame's violet still grows wild. Like foxgloves, it's in drifts that it works best.
