Cardamine flagellifera, commonly known as Blue Ridge bittercress,[1] is a species of herbaceous plant in the mustard family. It is native to eastern North America, where it is found primarily in the southern Blue Ridge.[1] It is a perennial that produces white flowers in the spring.[2]

Two varieties are sometimes recognized. These are:[1]
