BOG AND MARSH GARDENS 73 



American Sensitive Fern (Onoclea) are other suitable 

 forms. 



Quaint and interesting flowers there are in abundance, 

 as well as those of real beauty. The Marsh Helleborine, 

 for instance, with purplish flowers and handsome foli- 

 age, the Marsh Orchis (O. latifolia) and O. foliosa. 

 The Habenarias, orchids from North America, would 

 do well in damp corners. One of the best is H. fimbriata. 

 All these plants look best grown in somewhat isolated 

 clumps, and afford a striking contrast to flowers of 

 simpler habit. Cypripedium spectabile, already referred 

 to, deserves a well-shaded, peaty hollow entirely to 

 itself: it is too good a plant to mix singly with others. 

 Sarracenia purpurea, with its blood-veined trumpet leaves 

 and sinister aspect, might be taken as the evil genius of 

 the bog garden, a plant of ill-omen, from which some 

 deadly potion might be brewed. It is quite hardy, and 

 belongs to the family of Pitcher -plants. The Fritil- 

 laries, natives of our English water-meadows, would 

 soon become established in grassy patches near the 

 stream. 



On the mossy ground around the pools and in 

 crevices between the stepping - stones, the Sundews 

 (Drosera) would be quite at home. On beds of 

 Sphagnum they thrive splendidly. A few tufts of 

 Cotton Grass (Eriophorum), so plentiful on the brown 

 bogs of Ireland, should not be omitted. Of Heaths, 

 there is the Marsh Heather (E. Tetralix) and E. 

 hybrida, a beautiful variety flowering through the winter 

 and early spring. From the stream sides of the Sierra 

 Nevada comes a charming Saxifrage, S. peltata, unique 

 as to its target-like leaves and loose clusters of pale pink 

 flowers. The Rockfoils are not particular as to treat- 

 ment, and several other kinds, including the native 

 S. granulata, might be grown in the drier portions of 

 the bog. Soldanellas, Pinguiculas, Parnassia, and the
