American speedwell

''Veronica americana'', variously called ''American Brooklime'' or ''American Speedwell'', is a plant native to temperate and arctic Asia and North America where it grows in streams and bottomlands.

The plant can be confused with Skullcap and other members of the mint family. Members of the mint family have square sided stems, and ''Veronica'' species have rounded stems, and are easily distinguished from skullcap.
