In the garden
Epipactis gigantea is a terrestrial orchid from Canada south to Mexico that succeeds where soil remains consistently damp. In its native range it occupies riverbanks and wet meadows; in cultivation the same conditions are easiest to replicate at pond edges or in a deliberately wet border. Flowering takes place July to August and the blooms carry a mild, sweet scent that is noticeable on warm days. Position in partial shade or full sun depending on local exposure, but avoid open, drying sites; north, east or west aspects are all suitable. The species prefers moist to wet, well-drained sandy or loamy soils with a neutral to slightly acidic pH. Provide a sheltered to moderate exposure, which reduces stress on the shoots and helps retain soil moisture through summer. Use for water-garden margins, naturalised beds and wet meadows where other moisture-loving perennials are grown. Plant into soil that will not dry out and allow roots to remain cool and damp rather than waterlogged. Locate clumps where the flowering stems will rise just above the wet ground so the mild scent and summer blooms are easily seen and enjoyed in July–August.
