Perennial Rockcress (Boechera perennans (S.Watson) W.A.Weber)
Also classified as Arabis perennans S.Watson.
POWO has merged Arabis gracilipes Greene into this species, treating it as Boechera perennans subsp. gracilipes (Greene) Windham. However, we have held off on this merge because it is not accepted by any of the other authorities, including BONAP, FNA, and iNaturalist; we follow these other authorities' treatment of keeping them separate.

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
This species is also native to Mexico, but we have yet to build its map.
