Veronica filiformis, commonly known as the slender speedwell among other names, is a species of flowering plant in the family Plantaginaceae. It is native to northern Turkey and the Caucasus, and is known in many other regions as an introduced species, for example in the United Kingdom, where it began as a rock garden plant and later became wild. Veronica filiformis is a rhizomatous perennial herb producing mats of hairy stems. It is self-sterile and rarely seeds, being spread by stolons. The petals are four-lobed and blueish with a white tip, around 8–10 mm in diameter, the top lobe being largest since it is actually a fusion of two lobes. At the center are two long, protruding stamens. Solitary flowers occur in leaf axils. They are on relatively long, slender stalks that arise from the leaf axils, and appear between April and July.
