Synonyms: Narrow-leaved Bittercress.
Narrowleaf Bittercress is native to Europe. This non-native invasive mustard was first discovered in New Hampshire in 1916, and has since spread throughout the Northeast and west to eastern Minnesota. The first records from Maryland of Narrowleaf Bittercress appear around 2010 from along the Susquehanna River. Since then, Narrowleaf Bittercress has made its way down the Baltimore - Washington Corridor. Narrowleaf Bittercress grows in moist soils of rich woods. Ditch edges, seeps, and stream banks are favorable habitats.
Narrowleaf Bittercress can be differentiated from other Cardamine species by having stem leaves with seven or more leaflets. The stem leaves have sagitate-auriculate bases, and acuminate tips. Most other Cardamine species with seven or more leaflets on the stem leaves have leaflets that are mostly obtuse.
