Veronica repens
Creeping speedwell is a low, mat-forming perennial groundcover growing only 1 to 3 inches tall and spreading by rooting stems, with small, glossy bright green leaves. It prefers full sun to part shade with regular, even moisture and well-drained soil, and tolerates light foot traffic. Tiny pale blue to white flowers appear in spring, dotting the foliage. Use it as a small-scale lawn alternative, between stepping stones and pavers, in rock garden crevices, and as a fine-textured filler in moist, partly shaded plantings.
