THE NEW SUBURBAN GARDEN 221 



Flattish stones approximately two feet by eighteen 

 inches will be better than short, thick pieces, whether 

 round or square. These can be set in a series of small 

 terraces, as suggested in chapter v. With a stone here 

 and there set on end, with some showing more surface 

 above the soil than others, and with pockets of different 

 shapes and sizes, there will be no stiffness. 



The top should be planted with two or three of the 

 larger Rock Roses (Cistus), which will thrive in the 

 hottest situation, are evergreen, and have beautiful 

 flowers. For a description of the best kinds see chapter vi. 

 In good soil they will grow two feet high or more, and 

 go a long way towards hiding a possibly ugly fence. 

 If planted in autumn or early spring they will flower in 

 summer and make growth afterwards. 



The plants for the lower parts of the rockery should 

 be chosen from the most hardy and free-growing of the 

 kinds described in chapter vi. It is to be feared that 

 the Primulas will not thrive, nor will the mossy Saxi- 

 fragas, if the position is a very hot one ; but a few might 

 be tried in partial shade. Camposi (Wallacei) is one of 

 the best, and it is as likely to succeed as any. Vigorous 

 Canpanulas, such as Carpathica and turbinata and their 

 forms, will probably thrive. There could be few better 

 plants than these, for they are cheap, easily grown, 

 flower abundantly till the end of summer and give shades 

 of blue. Silene acaulis is a charming little plant that 

 would probably succeed. Most of the Sedums (see 

 chapter vi) would do well. Gypsophila repens is a free- 

 spreading plant with pretty flowers ; and its variety 

 rosea might be added. This is an inexpensive plant that 

 will grow almost anywhere, and soon fill a large pocket. 

 A few of the hardy Alpine Pinks should be planted, 

 particularly Dianthus deltoides.
