Thyme-leaved Speedwell

Scientific Name: Veronica serpyllifolia

Family: Scrophulariaceae (Figwort)

Thyme-leaved Speedwell is a perennial, common throughout the British Isles, preferring damp, acid soils. The dark green leaves are smooth and glossy, unlike the other Speedwells - some hairs can be found under magnification. They are arranged in opposing pairs along the ceeping stems which turn upwards and terminate in leafy flower spikes.
The white or pale blue flowers occur between March and October and are pollinated by small flies. The top petals have dark blue lines.

It is easily uprooted, there may also be a reservoir of seeds which will germinate later. Weedkillers are effective and any regrowth or new seedlings will require retreatment.

See also Selfheal, which has a similar growth habit and the other Speedwells - Common Field Speedwell, Germander Speedwell, Ivy-leaved Speedwell, and Slender Speedwell.
