CommentsOther common names of Veronica scutellata are Skullcap Speedwell and Narrow-Leaved Speedwell. This delicate wildflower is somewhat similar to Water Speedwell (Veronica anagallis-aquatica) and American Brooklime (Veronica americana); these species occupy similar wetland habitats and bloom at about the same time of year. Marsh Speedwell differs from the latter two species by its narrow leaves (less than ½" across). These native species should not be confused with introduced Veronica spp. that are weedy annuals. Species in this latter group prefer drier disturbed areas and they tend to be smaller in size with much shorter leaves.
