on gravel, tracks, banks, dunes, walls and pavements.
It also grows in the mortar of walls.
In grassland it may be confined to the drier, nutrient-poor
tops of anthills.
Wall Speedwell is a native, annual, prostrate and erect
herb, growing up to 30cm.
The flowers are deep blue and small, at 2 to 3mm across.
The calyx is bigger with the sepals longer than the petals.
The capsule is ciliate and about the same size as the
calyx.
Leaves are dark green, toothed and usually small,
although they may reach up to 1.5cm.

Wall Speedwell is variable in size and is best recognised by
the tiny, deep blue flowers and the small, dark green
leaves.
The seeds can remains viable in the soil for several years,
