Fingered Speedwell Plant Care

Fingered Speedwell (Veronica triphyllos) belongs to the Plantaginaceae family within the Veronica genus. Fingered Speedwell is native to Europe, western Asia and NW Africa. Fingered Speedwell is also known as Three-leaved Speedwell.

Fingered Speedwell displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Fingered Speedwell produces small, tubular flowers in shades of blue, pink, or white.

Leaf size: approximately 3 inches.

Water a young or newly planted Fingered Speedwell every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Fingered Speedwell thrives in full sun to partial shade.

Veronica triphyllos tolerates temperatures of 50–75°F. Fingered Speedwell prefers humidity levels of 40–60%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Fingered Speedwell to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fingered Speedwell every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Fingered Speedwell is suited to USDA Zone 6a – 9b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Fingered Speedwell can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fingered Speedwell while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Fingered Speedwell is hardy down to USDA zone 6a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Fingered Speedwell can be propagated through seeds, division of clumps. Similar propagation techniques also apply to field speedwell plant care, which shares the same genus.

Fingered Speedwell is susceptible to aphids, slugs, snails. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Fingered Speedwell grows outdoors in USDA Zone 6a – 9b. It survives winters down to planting zone 6a. Fingered Speedwell is native to Europe, western Asia and NW Africa.
