Veronica persica (common names: birdeye speedwell, common field-speedwell, Persian speedwell, large field speedwell, bird's-eye, or winter speedwell) is a flowering plant in the family Plantaginaceae. It is native to Eurasia and is widespread as an introduced species in the British Isles (where it was first recorded in 1825), North America, and eastern Asia, including Japan and China.
Veronica persica is an annual or winter annual herb that reproduces from seed.
Its cotyledons are triangular with truncated bases. The short-stalked leaves are broadly ovate with coarsely serrated margins, and measure one to two centimetres (0.4 to 0.8 in) long. The leaves are paired on the lower stem and are alternately arranged on the upper parts. The plant has weak stems that form a dense, prostrate groundcover. The tips of stems often grow upright.
The flowers are roughly one centimetre (0.4 in) wide and are sky-blue with dark stripes and white centers. They are zygomorphic, having only one vertical plane of symmetry. They are solitary on long, slender, hairy stalks in the leaf axils.
Although many species in the genus are used in gardens (such as V. exalta, V. incana, V. gentianoides, V. longifolia, V. perfoliata, and V. spicata), this species is generally seen as a weed and has no known horticultural uses.
