BEAUTIFUL FLOWERS 



in a box in a frame or greenhouse, 

 but failing that out of doors in early 

 summer. Or they may be propagated 

 by division. 



(i) Saxifragas. The "Rockfoils" are a 

 large and very important genus of 

 rockery plants indeed, many would 

 consider them the most important of 

 all. They vary considerably in height 

 and habit, some being quite moss-like, 

 and others having tall flower stems. 

 Oppositifolia major, purple, may be 

 taken as an example of the former ; 

 and cordifolia pyramidalis, red, of 

 the latter. There are many spring- 



flowering Saxifragas besides these, 

 and three of the best of them are 

 aizoon, cream; granulata, white; and 

 Wallacei, white. The latter is a 

 charming little rock gem, bearing its 

 pretty flowers in great profusion. 

 The Saxifragas are propagated by 

 division in autumn. 



Triteleia uniflora. A quaint lilac flower, 

 procurable from bulb-merchants in 

 autumn. 



Veronica chamaedrys. This member of a 

 greatly varying genus, which includes 

 many large shrubs, is suitable for the 

 rockery. It has blue flowers. 



SUMMER-FLOWERING PLANTS 



Several of the genera that we have already considered give us 

 summer-flowering species, and in addition there are many others. 



( i ) A rmeria cephalotes. Most people know 

 this beautiful, grassy-leaved, bright- 

 flowered edging plant. There are few 

 prettier, whatever their cost, and it is 

 as well worthy of being introduced to 

 the rockery as if it had never graced 

 a cottager's flower border. Propa- 

 gated by division. 



Aster (Michaelmas Daisy). There is one 

 species of this splendid genus which 

 is suitable for the rockery, and that 

 is the purple-flowered alpinus; the 

 majority are too large. It is a very 

 pretty Daisy, and may be increased 

 by division in spring. 



(i) Campanulas (Harebells). This is an- 

 other of the great rockery genera, and 

 the flower gardener will find it almost as 

 valuable as the Pinks, Phloxes, Andro- 

 saces, and Saxifragas, in spite of (or 

 perhaps because of) the fact that the 

 species are mostly blue in colour. 

 One or two, such as carpathica and 



(i) Androsaces. These are extremely popu- 

 lar with lovers of rock plants, on 

 account of their brilliant colours and 

 charming flowers. They are particu- 

 larly dainty and pleasing, both in 

 growth and bloom, and must be re- 

 garded as among the choicest of our 

 rockery gems. Perhaps carnea, rose- 

 coloured, is the best known, but 

 lanuginosa and villosa, which are of 

 much the same colour, run it closely. 

 The Androsaces are worthy of a little 

 special attention, and should be given 

 selected positions and good soil. They 

 can be increased by division in autumn 

 or winter, and also by seeds sown in 

 spring. 



Arenaria (Sandworf). This white-flowered 

 plant is not one of the highest class, 

 but it is useful, because it will thrive 

 in light, dry soil, which does not suit 

 many of the choicer Alpines. Pro- 

 pagated by division.
