Note

The only image currently available was one I took at the base of the summit cliffs of Ben Lawes and shows the upland subspecies humifusa, which has brighter blue and larger flowers. The seed supplied, however, will be Veronica serpyllifolia subsp. serpyllifolia, characterized by paler blue flowers and smaller blooms.

Description

Thyme-leaved Speedwell is a low, creeping native perennial. Its plain green, hairless leaves grow in opposite pairs along the stem and resemble large thyme leaves, as the common name suggests. The shoots produce short flower spikes bearing tiny pale blue or white flowers, each about 5–6 mm across. As the shoots rarely rise above 5 cm the plants are easily overlooked but close inspection reveals their delicate beauty. Flowering begins in late March and can continue through November.

Habitat information

Veronica serpyllifolia subsp. serpyllifolia is most commonly found in floodplain and upland meadows but also occurs in diverse habitats such as pasture, woodland rides, tracks, heaths, garden lawns, and waste ground. It tolerates a wide range of soil pH and fertility but does not thrive in deep shade. The species benefits from occasional disturbance—such as flooding, soil movement, or trampling—to maintain its presence.

Pollination is primarily by small insects, especially flies, though the plant is also capable of self-pollination.

Growing information

Sow autumn or early spring. Create and area of bare soil in which it can establish and do not cover but press onto the soil surface.
