Royal helleborine
Epipactis atrorubens
Royal helleborine is a specialist woodland orchid that requires a carefully prepared, well-drained calcareous soil with dappled shade to thrive. It depends on specific mycorrhizal fungi in the soil and does not transplant easily, making it best suited for established woodland or rock garden settings. Avoid overwatering and do not disturb the root zone once planted.
