The Story
Plant Bio
Epipactis helleborine, the broadleaf helleborine, is a terrestrial perennial orchid forming small colonies of unbranching upright stems from short underground rhizomes. The stems bear alternate, clasping, dull green leaves with prominent parallel veins, topped by long, somewhat one-sided drooping racemes of up to fifty small flowers.
The flowers display a subtle blend of dull green suffused with pink, purple, or brown, featuring a lower lip with a dark, nectar-filled basal sac. This highly adaptable orchid spreads readily via wind-dispersed seeds and vegetative expansion, often naturalizing in disturbed soils, lawns, and woodlands.

Planting
How to Grow
- Select a planting site in partial to full shade with moist, organic-rich soil.
- Plant dormant root plugs or potted specimens in spring, ensuring the crown sits just below the soil surface.
- Water regularly during the first growing season to maintain consistent moisture.
- Leave the upright stems undisturbed through summer and early fall to allow natural seed dispersal.
Pro Tip
Allow the foliage to die back completely naturally in late fall; cutting down the green stems prematurely in summer deprives the underground rootstock of vital energy.

Care Guide
Do
- Provide consistent moisture during the active summer growing season.
- Allow foliage to yellow and die back naturally in late fall.
- Grow in shaded woodland gardens or areas with organic-rich soil.
Don't
- Do not apply heavy fertilizers, as supplemental feeding is unnecessary and counterproductive.
- Do not plant in waterlogged or poorly drained soils where stagnant water collects.
- Do not cut back green stems prematurely during the summer months.
