Pyrola rotundifolia aka Round Leaf Wintergreen

Pyrola rotundifolia is an evergreen wildflower called round-leaved wintergreen. It belongs to the heath family, Ericaceae. Its native range spans temperate Eurasia into northern Indo-China. It is native to Britain and Ireland as well. Wild plants grow in bogs, fens, woods, and damp dune hollows. They often grow near limestone, including in beech woods.

This perennial forms upright clumps and spreads at a slow pace. Garden plants reach 0.5–1.25 feet [0.15–0.38 metres] tall. Their spread is about 0.5–1 foot [0.15–0.30 metres]. The leaves form a rosette at the plant's base. Each simple leaf is rounded to egg-shaped, with a glossy, leathery surface. The edges have rounded teeth or shallow lobes. Leaf stalks can match the leaf blades in length. Smooth stems range from green to green with red tones.

Small flowers hang down in racemes from May to August. Each bell-shaped bloom has five petals. Flowers are white or pink, with a scent that recalls almonds. Bees visit the blooms. The fruit is dry and splits apart when ripe. The lasting leaves and scented flowers give this small plant garden value. It suits woodland beds, path edges, and planting in groups. It can form ground cover, but takes time to settle. Dense cover depends on strong growth rather than quick spread.

Choose a cool site with partial shade or dappled light. NC State also lists full sun among suitable conditions. Sandy or loamy soil suits it, with leaf matter or peat. The soil should stay moist through summer and may be wet at times. Neutral to alkaline soil suits it better than acid soil. NC State lists USDA zones 4–8. Plants For A Future reports survival down to at least −20°C. This is a difficult plant to establish, despite its cold tolerance. It depends on a mycorrhizal partnership with fungi in the soil. Its roots dislike disturbance, which makes division hard. Raising plants from seed is difficult too.

NC State lists no known pest or disease problems. The main growing challenges concern its roots and fungal needs. The leaves have a history of medicinal use. Plants For A Future gives it no food-use rating and lists no known edible uses. That source reports no known hazards, but this does not establish safety for people or pets. Its medicinal history should not be read as proof of safe home use.
