Veronica americana is found in western, northern, and northeastern states in wet areas.  It often occurs in large numbers, sprouting new plants from the roots of older plants.  Flowers are only 5-10 millimeters across and are borne in long racemes that emerge from leaf axils.

Ludwig Schweinitz (1780-1834) named this plant before his death, but the name was not published until 1846.

Veronica americana and Veronica anagallis-aquatica are very similar plants. V. americana's leaves have petioles; Veronica anagallis-aquatica has sessile leaves.

Both species enjoy the same boggy, streamside habitat and both grow to about fourteen inches tall with numerous, tiny, blue-white flowers.

Linnaeus named V. anagallis-aquatica in 1753 from European specimens.  Pennell named V. catenata in 1921.  Weber, Welsh, and Cronquist list these as separate species; Kartesz, the ultimate authority for all names on this web site, indicates that these are one and the same species.
