when the roots are in contact with a perpendicular rock, 

 or with the sides of the pot. Amongst other hardy orchids 

 well worthy of notice are Cypripedium acanle, calceolus, and 

 spectabile, Epipactis grandiflora, Ophrys apifera, fucifera, and 

 lutea, Orchis incarnata, inaculata, nigra, and pyramidalis, and 

 wherever an alpine border is contemplated these orchids ought 

 to find a place.
