HARDY ORCHIDS 119 



moment for a young and wilful enthusiast. In such a spot, 

 Mocassin Flowers can be seen at home at their real best. But 

 I am not sure since we cannot in our English gardens 

 emulate the wild luxuriance and tangle of the native bog, 

 which is picturesque, but malarial withal whether the most 

 enjoyable way of growing such bog plants is not on the 

 lines I have here ever so slightly suggested, so seldom is 

 it that one sees them entirely at their ease in the bog-bed. 

 Two or three species of these hardy Cypripediums have yellow 

 and brown flowers, such as our own rare C. calceolus, 

 reputed intractable under cultivation ; C. parviflorum, smaller- 

 flowered, but elegant with its twisted petals and sepals ; 

 and C. pubescens, a stronger-grower than either, easier to 

 manage, and fairly plentiful. A scarcer North American 

 species, C. candidum, has a white lip, with sepals and petals of 

 greenish brown. There are, besides, other hardy Cypri- 

 pediums worth growing ; for example, the somewhat uncanny- 

 looking Siberian C. macranthum, with its large purple pouch ; 

 and the stemless red-flowered C. acaule. 



Associated with these for, though they are not Orchids, 

 they company together by nature one or two species of 

 Sarracenia would be very fitting to cultivate, being seldom 

 quite satisfactory in the open garden, as the pitcher-shaped 

 leaves generally become torn and disfigured. S. purpurea, the 

 typical Huntsman's Cup, and S. flava are two of the hardiest. 

 This hardy section of Sarracenia would offer a field for 

 hybridisation quite as interesting as the tender species which 

 have already been taken in hand by experts with such 

 gratifying results, as may be seen any spring day at Kew, in 

 the annexe devoted to such plants. 



The Disas, again, which take rank among the finest 

 Orchids, are pre-eminently amenable to cool treatment. 

 D. grandiflora, one of the glories of Table Mountain, when 

 it has donned its fine scarlet coat, lives with its roots in the
