Most Speedwells have blue flowers and Wall Speedwell (Veronica arvensis) is no exception. And its flowers are really tiny.
As is also the whole plant, here early in the season in a dry meadow.
In its corolla the petals are joint together to form a kind of funnel. Every plant makes a lot of flowers but because they are short-lived and easily fall off you mostly see buds and fruits.
The fruits are heart-shaped with often a remnant of a style still visible. The stalks get longer after flowering to make place for all those fruits.
Wall Speedwell is a common plant. As it name says, it grows on top of stone walls but also in fields, gardens and open spaces in meadows. Or as here in a spot where last year someone made a fire of branches.
