Part II. SAXIFRAGA. 311 



also excellent for planting on ruins and old walls, on which the 

 seed should be sown in mossy chinks in spots where a little 

 soil has gathered. It is also a valuable border-plant, formingi 

 roundish spreading cushions, with masses of flowers, and is well 

 worthy of being naturalised in bare and rocky places. A native 

 of Southern and Central Europe in stony and rocky places, and 

 although it grows freely in poor soil when it is planted with the 

 view of allowing it to fall freely over the face of a rock, a greater 

 development will be secured by putting it in deep rich loam. 



One or two other dwarf Saponarias have recently been intro- 

 duced to our gardens, S. liitea and .S". ccespitosa, for example. 

 The former of these is not worthy of cultivation except in S. 

 botanic garden, and the last insufficiently tried. 



SAXIFRAGA hJZ.OYD'E&.— Yellow Mountain Saxifrage. 



A NATIVE plant, very abundant in Scotland, the North of Eng-v 

 land, and some parts of Ireland, in wet places, by the sides of 

 mountain rills or streams, and often descending along their 

 course, into the low country, producing at the end of summer 

 or autumn an abundance of bright yellow flowers, half an inch 

 across, and dotted with red towards the base. It forms dense, 

 dwarf, bright green masses of leaves, and has leafy branched 

 flower-stems, by which it is distinguished from the other yellow 

 native Saxifrages. Although a moisture-loving mountain plant, it 

 is quite easy to grow in lowland gardens, naturally doing best in 

 moist ground. Wherever a small stream or rill is introduced 

 to the rock-garden or its neighbourhood, it may be most appro- 

 priately used, and planted so as to form wide-spreading masses, 

 as it does on its native mountains. Easily propagated by divi- 

 sion or by seed. When the leaves are sparsely ciliated, it is, 

 according to Mr. Sytne, the S. dutumnalis of Linnseus. 



SAXIFRAGA KIZOOTS .—Aizoon Saxifrage. 



Not a pretty-flowering kind, having a greenish-white bloom, 

 but it spangles over many a low mountain crest and high alp- 

 flank in Europe and America with its silvery rosettes, and in 

 our gardens these form such firm, compact, and roundish silvery 

 tufts in any common soil that it deserves to be universally culti-
