EASY ROCK AND WALL GARDENING 99 



discovered afterwards was Calochortus, a Lily from Cali- 

 fornia, which is supposed to require a good deal of warmth 

 and some care, so we were very proud of his appearance 

 in our rockery. 



We contrived to find room for many pretty things : 

 Campanula Bavaricay in falls of azure blue ; the white 

 Iberis and Arabis, double and single ; yellow Alysum ; 

 Aubrietia, pink and mauve ; as well as one or two Rock 

 Pinks and some crimson Thrift. The Bird's-eye Prim- 

 rose, and Rock Primulas, and Alpine Poppies (these are 

 lovely), we could not run to for want of space. 



Saxifrages are a blessing in the shady rockery. Here, 

 as well as the sunshiny one, mossy and encrusted Saxi- 

 frages do very well. Some of the mossy Saxifrages are 

 early bloomers, opening in February with large white 

 flowers, in striking contrast to their tufted dark-green 

 leaves. The encrusted Saxifrages are the most wonderful 

 of rock-plants ; any one unfamiliar with their shining 

 silver edges might fancy the foliage were frosted ; but 

 the edging is really an incrustation of lime. In some 

 form or other lime is a food these plants must have, or 

 they cannot thrive ; it is pretty to see them using their 

 food-stufF to adorn themselves as well as in support of 

 life. Some small Saxifrages we liked are S. sancta^ with 

 yellow flowers, S. oppositifolia^ with red-purple blooms, 

 and the double-flowered native S. granulata. Perhaps 

 the handsomest of all is 5. longifolia^ which grows in huge 

 rosettes, throwing from the centre of each a panicle of 

 creamy white flower nearly two feet long. 



Wall-planting is easier to manage in the small garden 

 than the rockery because it so economizes space. Many, 

 in fact most, rock-plants do well in walls if made with 

 mould enough to give root-room. A double wall is a 

 delightful thing. On the broad top of it Roses can be 

 planted, and soft-stemmed Roses look even prettier when 

 falling down than when climbing up. Pink blossoms are
