This pretty plant is an Eveline veronica. Veronica is named for
St Veronica who comforted Jesus on his path to Calvary.

Eveline veronica has pinkish-purplish flower spikes
from May until July. It grows to about two feet in height and about a
foot in width. dead-heading will encourage reblooming. Veronica benefits from consistently moist soils during the growing period but cannot tolerate wet soils during dormancy. It is unattractive to both deer and rabbits.
