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.


BONAP has merged stemless spiderwort (Tradescantia subacaulis) into this species, but we have not; this explains the absence of this species in our map from the Southern Texas Plains. Besides this there are no significant differences in range maps, as a result of this classification difference, that are visible at level 3 ecoregions.
