Thyme-leaved Speedwell
Latin: Veronica serpyllifolia
Irish: Lus an treacha
This is a native Veronica species. It is a hairless perennial with a short creeping stem and upright flowering branches. Its normal habitat includes waste places, lawns, cultivated areas and roadsides.
The leaves are slightly toothed, oval, have very short stalks and grow in opposite pairs. The flowers, which appear from May onwards, are small (about 6mm across) and have 4 light blue or, sometimes, white petals with dark veins.
Collected in the Builder’s Paddock during May when the plant was in flower.
