Scrophulariaceae
Plants in the genus Veronica are native to a wide variety of habitats: moist meadows and grasslands, dry, sunny meadows, rocky hillsides, and scree, and open woodland. They bear small, outward-facing flowers in blue, purple pink, or white with conspicuous stamens. Mat-forming species are perfect for a rock garden, alpine house or a trough. Larger species are suitable for the edge of a mixed, herbaceous border.
Noteworthy characteristics:  In some species, long racemes or spikes look like elegant candles that are lit from the bottom up.
Care:  Grow alpine species in moderately fertile to poor, well-drained soil in full sun. Protect species with felted leaves from winter moisture. Grow border species in moderately fertile, well-drained soil in full sun to partial shade.
Propagation: 

Sow seed in fall. Divide perennials in spring or fall. Take softwood cuttings of subshrubs in spring.

Problems: 

Scale insects, downy mildew, powdery mildew, rust, leaf smut, root rot.
