Dame's rocket is a garden plant that was introduced from Europe in colonial times. It now grows wild across much of the United States. Dame's rocket is sometimes confused with phlox, but note that its flowers have four petals, while phloxes all have five-petalled flowers. Dame's rocket is an invasive weed that threatens native plant habitats. More on this topic from Invasive Plant Atlas of New England.
