[PART II. 



in summer, are numerous, whitish-yellow, 

 arranged in a loose panicle. Similar 

 in growth are S. aspera, S. bryoides, 

 S. sedoides, S. Seguieri, S. Stelleriana, 

 and 8. tricuspidata, all of which are 

 suitable for clothing the bare parts of the 

 rock-garden and slopes, but require moist 

 soil and cool positions. Division in spring 

 or the end of summer. 



Saxifraga umbrosa (London Pride). 

 This much cultivated plant grows abund- 

 antly on the mountains round Killarney, 

 though it was much grown in our gardens 

 before it was recognised as a native of 

 Ireland. It is needless to describe the 

 appearance of such a familiar plant. It is 

 useful in shady places, fringes of cascades, 

 &c. There are several varieties, as, for 

 example, S. punctata and Serratifolia, 

 which are distinct enough when grown side 

 by side, and submit to the same culture. 



It is believed that the preceding 

 are among those best worth growing. 

 The following is a list of the other 

 species or reputed species believed 

 to be in cultivation now in this 

 country. Those most worthy of

 ous). A handsome plant, flowering from 

 early summer to late autumn, a true 

 perennial on warm soils, but often perish- 

 ing on cool soils. It forms dense tufts, 

 which yield many blue flower-heads, each 

 usually from 3 to 4 inches in diameter, 

 on long foot-stalks. There is a white 

 variety. Caucasus. Division and seed. 



S. graminifolia (Grass-leaved S.). A 

 graceful Scabious about a foot high, with 

 pale blue flowers and silvery white 

 leaves ; it is very useful for the rock- 

 garden. Southern Europe. June to 

 October. Division and seed. 



S. pterocephala (Wing-headed S.) is 

 a very dwarf-tufted hardy perennial, 

 rarely exceeding 4 inches or 6 inches in 

 height, even when in flower ; flower-heads 

 | pale purple in summer. Greece. Division. 

 Syns., S. Parnassi and Pterocephalus

S. Webbiana is another useful species 

 for the rock-garden or border, forming 

 neat little masses of hoary leaves. Its 

 creamy yellow flowers, borne on long 

 stalks, are pretty from July to August. 

 Division. 



All the rock Scabious are best in light 

 and well-drained soils.
