192 ROCK GARDENING FOR AMATEURS 



The colouring, brownish-green, is not showy, but the 

 mimicry, in the resemblance of the flower to a bee, is 

 very striking. It should be grown in a sunny spot, in 

 turfy soil containing limestone. 



The curious Man Orchis (Ophrys anthropophora) is 

 of greenish colour, with yellow lip, while the Spider Orchis 

 (Ophrys aranifera), of green and brown shades, is also 

 very curious, if not remarkably attractive. Both these 

 need loam containing chalk or limestone. 



Gymnadenia (Habenaria) bifolia is our native Butterfly 

 Orchis. It is about twelve inches high, and has small 

 white flowers. G. conopsea and G. odoratissima have 

 purplish fragrant blossom. They bloom in May and 

 June, and thrive in peaty soil in half-shade. 



Serapias is an interesting hardy Orchid from Southern 

 Europe, suited only to gardens in warm districts. Serapias 

 lingua is, perhaps, the chief species ; it grows some twelve 

 inches high, and bears reddish-lilac blooms in May. 

 This Orchid thrives best in a sunny spot in sandy loam 

 containing limestone.
