themum), Dwarf Phlox (P. subulata and others), yellow 

 Alyssum, Alpine Pinks, especially Dianthus caesius, 

 deltoides, and plumarius, some of the Bellflowers, notably 

 Campanula garganica, Portenschlagiana, carpatica, and 

 pusilla all these will form drooping masses of leaf and 

 blossom, and should be allowed plenty of room. Then 

 there are Erinus alpinus, a purple drift in spring ; Silene 

 alpestris, a beautiful little white-flowered Catchfly ; 

 Gypsophila repens and rosea, Saponaria ocymoides, 

 Acaena Novae Zealandiae, the brilliant blue Veronica 

 rupestris, Sedums and Sempervivums (Houseleeks), the 

 lovely Arenaria montana and Saxifraga Wallacei. These 

 exquisite and easily grown flowers are suitable, and all 

 will be found described in another part of the book. 

 For shady corners there are the Mossy Saxifrages, Arenaria 

 balearica, that creeps, a fairy leaf tracery, over the rock 

 face, Arenaria caespitosa, ferns in variety, and Foxgloves. 



Beautiful grey-leaved plants are the Silvery-leaved 

 Saxifrages (more fascinating than ever when in bloom), 

 Thymus lanuginosus, Sedums Ewersi and spathuli- 

 folium, and Cerastium. 



Seeds may be sown of the little purple and orange 

 Alpine Toadflax (Linaria alpina), Vittadenia triloba, 

 with pink, Daisy-like blooms; Tunica Saxifraga, that 

 becomes a cloud-like mass of tiny pinkish flowers in 

 September ; and Oenothera missouriensis, a fine, big pale 

 yellow Evening Primrose. All these are likely to bloom in 

 summer if seeds are sown in early spring. Then there are 

 Wallflowers, Snapdragons, Foxgloves, Mulleins, and others.
