Did you know?
This is the only species of Boechera in North America that has pick-shaped hairs on the lower stem. Even though it is an obvious biennial in our area, there are certain locations in the mountains of the West where the plants are definitely perennial. The common name refers to its former scientific name, "Arabis drummondii", after Thomas Drummond, an early 19th century Scottish botanist who explored the Rocky Mountains and southern U.S. "Boechera", the new genus name, is after the Danish botanist Tyge W. Bocher.

| State Ranking Justification |
[-] |
There are 11 current populations but most of them have fewer than 100 plants each. There are more than 30 historical populations, so more occurrences are expected to be found.
The short-term trend seems stable but only a few occurrences have been revisited in recent years. Population sizes fluctuate, so more years of survey are needed to accurately determine short-term trend.
There were over 30 historical populations known throughout the state, but only 10 populations are currently documented. The long-term trend seems to indicate a decline, but more surveys of historical records may discover that this trend is not severe.
