 brilliant ; Kaiifmanniana, red, white and yellow ;

 linifolia, scarlet ; and primulina, red and yellow. 



TUNICA SAXIFRAGA.—A tufty little Alpine, 

 bearing white or pale pink flowers for a long 

 period in summer. It will grow in almost any 

 soil, and in dry places. It may be raised from seed 

 in spring. 



VERONICA. — ^This immense genus of herbs and 

 shrubs comprises a few useful Alpines, but the great 

 majority of the species are far too large and coarse 

 for the rockery. Some are shrubs which, growing on 

 suitable soil (and they love limestone) will become 

 several feet through in a few years. Alpine species 

 will thrive in ordinary garden soil, and may be increased 

 by division in spring. The following might be used : 

 corymbosa, blue, flowers in autumn ; gentianoides , blue, 

 flowers in early summer, there is a variegated variety 

 (variegata) ; and spicata, blue, flowers in summer. 

 There is a prostrate kind called repenSj which carpets 

 the ground, and bears blue flowers in spring. The 

 handsomest of all the herbaceous species is longi folia 

 subsessiliSj but it is rather too large for the rockery, 

 and ought to be grown in the border. Veronica 

 Chamaedrys is the Germander Speedwell, a British 

 plant not unworthy of a place in the rockery. Incana, 

 which forms a silvery carpet and bears violet flowers 

 in July, is good. Cupressoides is an interesting 

 shrubby species.
