Damask-violet

Dame's rocket (Hesperis matronalis) is a vigorous, fragrant-flowering plant that produces showy clusters of purple, pink, or white blooms in late spring and early summer. Plant it in average, well-draining soil in a sunny to partly shaded spot and water regularly during its first season to establish strong roots. It self-seeds freely, so deadhead spent flowers if you want to limit its spread in the garden.
