Euphrasia hirtella Plant Care

Euphrasia hirtella (Euphrasia hirtella) belongs to the Orobanchaceae family within the Euphrasia genus.

Euphrasia hirtella displays a low rosette, clumping growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Euphrasia hirtella produces small, delicate flowers in shades of purple, white, or yellow.

Leaf size: approximately 2 inches.

Water a young or newly planted Euphrasia hirtella 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.

Euphrasia hirtella thrives in partial shade to full sun.

Euphrasia hirtella tolerates temperatures of 60–75°F. Euphrasia hirtella prefers humidity levels of 40–60%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Euphrasia hirtella to prevent waterlogging, which leads to root rot and fungal issues.

Feed Euphrasia hirtella 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 partial shade to full sun and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Euphrasia hirtella is suited to USDA Zone 13a.

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.

Euphrasia hirtella can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Euphrasia hirtella 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.

Euphrasia hirtella is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Euphrasia hirtella can be propagated through seeds, division of clumps. Similar propagation techniques also apply to wood eyebright plant care, which shares the same genus.

Euphrasia hirtella is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Euphrasia hirtella grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Euphrasia hirtella as a houseplant or bring it indoors before the first frost.
