Syrian Speedwell Plant Care

Syrian Speedwell (Veronica syriaca) belongs to the Plantaginaceae family within the Veronica genus. Syrian Speedwell is also known as Creeping Speedwell.

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

Leaf size: approximately 3 inches.

Water a young or newly planted Syrian 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.

Syrian Speedwell thrives in full sun to partial shade.

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

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

Feed Syrian 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.

Syrian Speedwell is suited to USDA Zone 12a.

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.

Syrian 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 Syrian 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.

Syrian Speedwell is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

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

Syrian 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.

Syrian Speedwell grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Syrian Speedwell as a houseplant or bring it indoors before the first frost.
