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.
It is a herbaceousperennial with glabrous stems 10–100 cm long that bear terminal or axillary racemes or spikes of soft violet flowers. The leaves are 1.5–8 cm long and 3 to 20 times as long as wide, short-petiolate, glabrous, serrate to almost entire.
The plant can be confused with Scutellaria (skullcap) and other members of the mint family. Members of the mint family have square sided stems, and Veronica species have rounded stems.
