78 ROCK GARDENING FOR AMATEURS 



be excluded from the small one. The moisture-loving 

 Primulas are a host in themselves : Primulas japonica, 

 pulverulenta, involucrata, Cockburniana, farinosa, Bul- 

 leyana, and many others will delight in it. The Summer 

 Snowflake (Leucojum aestivum) is happier there than 

 in a border, and if a carpeting plant is wanted over the 

 bulbs, the golden-leaved Creeping Jenny (Lysimachia 

 Nummularia aurea) is excellent. Wood Lilies or Trilliums 

 are lovely in the bog garden ; so, too, are some of the 

 hardy Orchids, such as Cypripedium spectabile, Orchis 

 foliosa, besides some of our native kinds. If free-growing 

 plants are wanted, some of the Musks may be added. 

 Gentiana verna will thrive there, especially if some stones 

 are put about the plants. Saxifraga Hirculus major, 

 with S. aizoides and its variety aurantiaca, are happy 

 in the little bog garden ; so, too, is the choice violet-blue 

 Pinguicula grandiflora, while a number of little peat- 

 loving shrubs, mentioned elsewhere, will grow there.
