flowers. From the same region comes S. Stribrnyi, with 

 a branching inflorescence covered with white hairs. 

 S. media comes from the Pyrenees. It has erect stems and 

 smaller rosettes with recurved leaves. These are best 

 grown in limestone fissures where there is little soil, 

 but where the roots can travel far in search of moisture. 

 All Saxifrages of this section are readily raised from 

 seed, which should be sown in sandy soil in spring. The 

 seedlings are very small, and must be left in the seed 

 pots until large enough to handle well. Cuttings should 

 be taken in summer, inserted in sandy soil, and kept in 

 a closed frame until rooted. 



OPPOSITIFOLIA SECTION 



The plants of this section, botanically known as 

 Porphyrion, have prostrate creeping stems, which root 

 into the soil and quickly form large mats of brown 

 stems, clothed with tiny rosettes of deep green leaves. 

 The best, S. oppositifolia, is a native of the European 

 Alps, and found also on some of the highest mountains 

 in Britain. It should be grown in a partially shaded 

 position, planted in gritty soil, with which leaf-mould 

 is freely mixed, and kept moist, especially in early summer. 

 Here it will produce its lovely rosy purple flowers in plenty 

 during the early spring. S. o. alba has pretty white 

 flowers, whilst the largest form is S. o. pyrenaica, some- 

 times called major, or maxima, with very large richly 

 coloured flowers. S. retusa, from the Pyrenees, is a 

 minute kind with crimson-purple flowers, the whole plant
