Roundleaf wintergreen Plant Care

Roundleaf wintergreen (Pyrola rotundifolia) belongs to the Ericaceae family within the Pyrola genus. Roundleaf wintergreen is native to Europe, Japan, Mongolia, Myanmar, Vietnam and Russia. Roundleaf wintergreen is also known as Round-leaved wintergreen, Wintergreen.

Roundleaf wintergreen displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Roundleaf wintergreen produces small, bell-shaped white or pink flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Roundleaf wintergreen every 3–5 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.

Roundleaf wintergreen thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Roundleaf wintergreen in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Pyrola rotundifolia tolerates temperatures of 50–70°F. Roundleaf wintergreen prefers humidity levels of 40–60%.

Moist, acidic, well-draining soil rich in organic matter like peat moss and pine bark. Good drainage is essential for Roundleaf wintergreen to prevent waterlogging, which leads to root rot and fungal issues.

Feed Roundleaf wintergreen every 8 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 to full shade and moist, acidic, well-draining soil rich in organic matter like peat moss and pine bark. Avoid low spots where water collects after rain.

Roundleaf wintergreen is suited to USDA Zone 2a – 7b.

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.

Roundleaf wintergreen 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 Roundleaf wintergreen 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.

Roundleaf wintergreen is hardy down to USDA zone 2a, 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.

Roundleaf wintergreen can be propagated through division, seeds. Similar propagation techniques also apply to liverleaf wintergreen plant care, which shares the same genus.

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

Roundleaf wintergreen grows outdoors in USDA Zone 2a – 7b. It survives winters down to planting zone 2a. Roundleaf wintergreen is native to Europe, Japan, Mongolia, Myanmar, Vietnam and Russia.
