Differs from Veronica arvensis in that its bracts are longer than its flowers which are white in color. Veronica arvensis has bracts shorter than its blue flowers. Both these species may be distinguished from the other two species found on coastal prairie because they have sessile flowers in racemes subtended by bracts that look quite different from leaves lower on the stems. Veronica persica and V. polita have flowers on pedicells in the axils of leaves that resemble the lower stem leaves.
Seeds germinate well when freshly harvested (Dorph-Peterson 1924). Seeds stored in dry, cold conditions appear to after-ripen for 6 months (Kelly 1952).
It ranges throughout most of North America, where it is native, and is introduced in many other parts of the world.
Moderately moist meadows, streambanks, shores of lakes and ponds throughout Louisiana and most of Texas.
