Flowering - March - June.

Habitat - Disturbed areas including lawns and roadsides.

Other info. - Steyermark's 1963 Flora of Missouri listed this plant in only five counties. Since then it has spread like wildfire, and is now perhaps the dominant Veronica to be found in the state, at least in the eastern region. It can be recognized by its scalloped, broadly ovate leaves and relatively long flower stalks. The corollas are typically pale to white toward their centers.
