Thyme-leaved Speedwell
Veronica serpyllifolia

Thyme-leaved speedwell is common on bare ground, gravel, edges of car parks, as a garden weed and can also be found in mountain scree. The flowers are around 5-6 mm in circumference and are white or pale blue with dark blue lines in the top petals. The leaves are without the hairy, toothed look of most small Speedwells and are glossy, smooth and more or less untoothed instead.
