Woolly Bluestar (Amsonia tomentosa Torr. & Frém.)

POWO shows a considerably larger range map for this species than USDA or BONAP; we have not yet investigated this discrepancy, but it is likely that the discrepancy reflects POWO having merged other populations into this taxon, which USDA and BONAP consider 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.
