FLOWER GARDEN AND ROCKERY continued. 



getting the stones well covered as quickly as possible, and to this 

 end should plant carpeters freely. Places may be provided for 

 broad patches of these. But it is well to guard against their en- 

 croaching on the pockets of weaker things and smothering the 

 latter. Arabises, Aubrietias, Cerastiums, Alyssum saxatile, Iberises 

 (perennial Candytufts), and many of the Saxifrages are beautiful 



Slants, and very useful for covering the surface of the soil quickly; 

 ut they must be kept within bounds. Alpines may be planted at 

 almost any period of the year, as dealers keep the best kinds in 

 pots ; but planting from the ground may be done any time between 

 autumn and spring when the ground is workable. Slugs are a 

 source of considerable trouble to the rock gardener, and it will be 

 found that they are the most abundant where a good deal of moist 

 cover is provided by coarse plants. The repression of exuberant 

 growth, and a periodical dusting with freshly-slaked lime, will keep 

 them under. Winter protection for Alpines : Alpines will endure a 

 great deal of cold, but those with woolly leaves are apt to suffer 

 severely from wet, and consequently it is wise to set small squares 

 of glass above choice kinds in order to throw off the rain. Plenty 

 of chippings round the plants will also serve as a preventive of loss 

 from damp. Alpines in shade : As we have seen, the great majority 

 of Alpine plants love the sun, but there are a few desirable plants, 

 notably Anemones blanda, Hepatica, and Robinsoniana, Campanula 

 Hendersoni, Cyclamens, American Cowslips, Corydalises, Epi- 

 mediums, Funkias, Gaultheria procumbens, Omphalodes verna, 

 Orobus vernus, Primulas Japonica and rosea, Saxifraga Geum and 

 the mossy varieties generally, Sisyrinchium grandiflorum, Thalic- 

 trum minus, Tiarella cordifolia, and the lovely white Wood Lily, 

 Trillium grandiflorum, which enjoy shade. It is often practicable 

 to provide that a certain part of the rockery shall have a northern 

 aspect; if not, stones must be used so as to form shady corners. 

 Selections of rock plants : The lover of Alpines learns about plants 

 by travel in mountain regions, by visits to large botanical gardens, 

 by inspection of collections at important flower shows, and by frater- 

 nising with amateurs of similar tastes. Meanwhile, beginners may 

 be glad of the following list:
