(Slender speedwell)
Low ground cover for sun or shade. Grows in dense mats that produce masses of light mauve-blue flowers in late spring. It is a fast grower but it is also easy to contain because it does not spread by seed. Very hardy in our zone 5, with no die back occurring in over a decade of growing it. Has become naturalized in Europe and parts of North America. Ht. 3-8cm (1-3in).
