Veronica crista-galli, the crested field-speedwell, is an annual flower in the family Plantaginaceae native from Iran north to the North Caucasus.

[1] An annual, bright blue flowered speedwell with a straggling habit (to 50 cm), superficially resembling, Veronica persica, with solitary flowers emerging from the stem with the leaf stalks, but its leaves have more numerous veins, flowers are shorter-stalked and smaller (generally smaller than the calyx it sits within), of a fairly uniform blue, and the calyx itself is formed of two, lobe-tipped parts, instead of the usual four unlobed parts; whilst the fruit when it matures is also concealed within the calyx rather than obvious, and has two parallel lobes, not divergent.

[2] Photographic examples can be seen on iNaturalist.

Its native range is Iran, North Caucasus, Transcaucasus, and is introduced in the British Isles [1] where it inhabits cultivated and rough ground and waste places.
