Veronica agrestis, the green field-speedwell [2] is a species of flowering plant in the Plantaginaceae (Plantain) family.

A sprawling, predominantly white to light blue flowered annual speedwell, sometimes lilac, with fresh green leaves.

The flower stalks are shortish (not clearly longer than the leaves), which mature to form a fruit capsule whose two lobes are parallel, clothed with long hairs or none, but lacking short hairs.

Similar species include Veronica polita (with dull green leaves, the lower leaves not elongated, its fruit with short as well as long hairs), Veronica persica (with flower stalks often much longer than the leaves, and the lobes of the fruit diverging like a 'V').
