Boechera stricta, or Drummond's Rock Cress, is native to the western United States, as well as most of the northeastern quarter. It is a biennial that grows in dry fields, openings, clear cuts, along woodland edges and in open, sandy woods. It blooms in mid to late spring, with bright white flowers.
This plant looks very similar to other members in the mustard family. There have been a number of reclassifications, resulting in confusing names and synonyms.
