CommentsThis small wildflower is one of several weedy Veronica spp. that have been introduced from Europe. Because of its small stature, it is not often noticed except when sizeable colonies of flowering plants are in bloom. Such colonies can produce an attractive display in lawns as the flowers are usually held above the blades of grass. Thyme-Leaved Speedwell can be distinguished from other Veronica spp. by its terminal racemes of flowers; it does not produce axillary racemes of flowers, nor does it produce individual flowers from the axils of true leaves (as opposed to the smaller leafy bracts). The leaf blades of Thyme-Leaved Speedwell are less toothed than those of many introduced Veronica spp., and it is a smaller plant than most native Veronica spp. While the native Veronica peregrina (Purslane Speedwell) is no larger than Thyme-Leaved Speedwell, the former species has flowers that are more white and its stems are hairless.
