Red Helleborine (Cephalanthera rubra) an orchid growing on limestone, protected everywhere in Europe and Red Data Book listed. It is extremely rare in the UK where it is on the edged of its range and has just a handful of sites it grows in light dry woodland...beechwoods, under oak and at the margins of pine and spruce forests. If leaf cover above it becomes too dense then the species reverts to a vegetative growth and stops flowering whilst being dependent upon the mycorrhizal fungi in its roots. Piediluco (Lago di Ventina), Umbria, Italy. July 2020.
