V. filiformis is a rhizomatous perennial herb producing mats of hairy stems that readily root at nodes that touch substrate.

The leaves, found near the base of the stem, are 5–10 mm across, rounded or kidney-shaped with blunt teeth and short stalks, and smaller on distal parts.

It is found in gardens, grassy paths and in meadows,[6] where it prefers shade, moist soils, good fertility and a low mowing height.

[9] The plant is used as groundcover in gardens, and valued for its pretty blue flowers, but it is easily dispersed into the environment if it is chopped up, during mowing, for example.

V. filiformis is similar to other Veronica species, such as V. arvensis and V. chamaedrys, but can be distinguished by the size of its leaves and lack of seed capsules.
