Hesperis matronalis L. Dame’s rocket, dame’s violet, mother of the evening, dames rocket
Members of the mustard family, dame's rocket is native to Eurasia, and naturalized in North America. "Dame's" is because they were favorites among women (these plants were introduced to North America for gardens); "rocket" for their fast spring growth. The fast-spreading plants are considered invasives in many areas. Identification: These plants typically have a two-year life cycle, though some persist for more than two years. In the first year, dame's rocket doesn't flower—it is just a mound of inconspicuous foliage. In the second year, plants reach up to 4' (1.2 m), composed of many hairy stems topped with groups of purple flowers. Flowers may also be lavender, pink, or white. Flowers are ¾-1" (1.9-2.5 cm) in diameter, and have 4 petals and a clove-like scent. It has alternate heart-shaped leaves, up to 4½" (12 cm) long and 1½" (4 cm) wide, with rounded serrations. Fruits are long, thin, upright pods, like anorexic beans. Some phlox varieties look similar, but their flowers have 5 petals instead of 4. Online References:
