Distinguished from V. polita by its flowers, which are 8-12 mm in diameter, and the lobes of its capsules, which are divergent. Veronica polita has flowers less than 8 mm in diameter and capsule lobes that are not divergent. Both these species may be distinguished from the other two species found on coastal prairie by having pedicelled flowers in the axils of leaves that resemble the cauline leaves. Veronica peregrina and V. arvensis have sessile flowers in racemes subtended by bracts that look quite different from leaves lower on the stems (see photo).
Seeds germinate well when freshly harvested (Dorph-Peterson 1924). Seeds stored in dry, cold conditions appear to after-ripen for 6 months (Kelly 1952).
