Pyrola rotundifolia is native to Europe, Asia, and Russia, where it colonizes alkaline wet sites, bogs, fens, and beech woods on limestone. Growing about a foot tall and wide, it produces bell-shaped racemes of fragrant pink-tinged white flowers from May through August, a long bloom season that rewards the considerable patience required to establish it. In American gardens it is genuinely hard to source, though seeds are occasionally available, and growing it from scratch is a project measured in years rather than seasons.

Like its relative P. elliptica, this plant depends on a mycorrhizal relationship with specific soil fungi and must be started in soil collected from around an established plant. It is also intolerant of root disturbance, making division a delicate operation. Given the right conditions, a peaty or leafy soil that stays cool and moist through summer in full sun or shade, it will slowly consolidate into a handsome ground cover for damp, alkaline sites where few other plants feel at home. The reward for persistence is a plant that flowers generously and asks for almost nothing once it has settled in.
