True to its name, this is one of the most common speedwells on campus. It is certainly much more common than the other field speedwells.
The common field speedwell (Veronica persica) turns up on wasteground and disturbed ground amongst other vegetation wherever there is plenty of light. The plants’ stems grow along the ground sometimes producing a thick mat. The bright, blue and white flowers are each held at the end of a long stalk that extends out well beyond the leaves.
Capsule shape, and the hairs on the capsules, are important diagnostic characters for speedwells. In the common field speedwell the v-shape between the two lobes of the capsule is very broad. The capsule hairs are held upright. Some of them are glandular and can be seen, under a hand lens, to have a small droplet of liquid at their tip.
