Discussion

Specimens of Veronica verna from Alberta have not been verified.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

In the flora area, Veronica undulata was introduced near ports (Mobile, Alabama, and Portland, Oregon) before 1900 via ship ballast from trade with Asia, did not spread much, and may not have persisted.
