Veronica americana, variously called American brookline 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 herbaceous perennial 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.
Uses and edibility
American speedwell is edible and nutritious and is reported to have a flavor similar to watercress
. Native Americans used Veronica
species as an expectorant tea to alleviate bronchial congestion associated with asthma and allergies. 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.
