Linnaea Plant Care

Linnaea (Polyachyrus poeppigii) belongs to the Asteraceae family within the Polyachyrus genus.

Linnaea displays a low spreading groundcover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Linnaea produces small daisy-like flowers in shades of yellow and white.

Leaf size: approximately 2 inches.

Water a young or newly planted Linnaea every 4–7 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.

Linnaea thrives in full sun to partial shade.

Polyachyrus poeppigii tolerates temperatures of 50–80°F. Linnaea prefers humidity levels of 40–70%.

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

Feed Linnaea 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Linnaea 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.

Linnaea can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Linnaea 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.

Linnaea 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.

Linnaea can be propagated through seeds, division of root ball.

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

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