Handsome plants ranging from less than an inch high to 2 ft. in height. Masses of small (1/4–1/2 in.-wide) flowers in white, rose, pink, or pale to deep blue make an effective display. Use in borders and rock gardens. Prostrate kinds are good between steppingstones and as bulb covers. Veronica (a perennial) is often confused with Hebe (a shrub).Veronica hybrids
