ALPHABETICAL LIST OF PLANTS 349 



S. Fergusoni {Group /., Mossy). — Practically a variety of S. Rhei. 

 A good red " mossy/' and about the earliest of that group to flower. 

 Blooms in March. 



S.fiorulenta {Group 11.^ Encrusted). — Requires a shady posi- 

 tion in a well-drained crevice in vegetable soil. Forms large 

 rosettes, 5 to 7 mches across, of dark green spiny leaves, withou; 

 a trace of the silver encrustation. Flowers pale lilac, in thrysoid 

 panicles. A very slow-growing species, taking several years to 

 mature the rosettes, from which the flower-spike rises. After 

 flowering the plant dies. A very difficult plant to grow. 



S. Fortimei. — Likes a partial shady position in gritty, well- 

 drained loam. Leaves reniform, cordate, dark green, and glossy. 

 White flowers in erect, many-flowered panicles. Blooms in October. 

 A pretty and useful plant on account of its late-flowering character. 



5. Frederici-Augusti {Group III.., Cushion). — Forms bluish, 

 rounded rosettes. Flowers small and pink, with purple-red calyces 

 borne in spicate heads ; the whole flower-spike covered with a dense 

 purplish-rose-coloured fur. A rare plant, rather like S. Griesbachi. 



S. Geuni {Group V., Umbrosd). — A species very near to S, u?nbrosa, 

 and a native, growing freely in Killarney. 



S. G, cochlea? is. — Is a dwarf variety. 



S. granulata. — Rather a distinct deciduous species, forming little 

 bulbs. Of vigorous growth, and spreading fairly quickly. It likes a 

 partially shaded position in gritty soil. Leaves reniform. Flowers 

 large and pure white, borne in heads on branching stems about 12 

 inches high. A pretty and easily grown plant. There is also a 

 double form which is very attractive. 



S. Griesbachi {Group III.., Cushion). — Forms compact rosettes, 

 glaucous blue leaves, with a silvery margin, from which rise in 

 February spikes of inconspicuous flowers, with crimson bracts. 

 The rosette from which the spike rises dies after flowering, but side 

 rosettes are formed. A distinctive plant, rather like S. Frederici- 

 Augusti. It is not difficult to cultivate. 



S. gutheiiana {Group F., Uinbrosa). — Very nearly allied to S. 

 Geinn., and has heads of white flowers. The variety S. g. va?iegata 

 has soft pink flowers, with a broad stripe of yellow on its glaucous 

 leaves. 



S. Hii-culus. — Requires a damp position in peaty soil. It is of 

 stoloniferous habit, with dark green leaves. Very beautiful, large, 

 bright yellow flowers in July. It is not an easy plant to grow, and 

 a shy bloomer. There is a form, S. H. major, which is finer, more 

 vigorous, and blooms more freely. 



S. Hostii {Group II., Enc7'usted). — Rosettes of narrow, dark grey- 

 green leaves, and numerous spikes of white flowers, spotted purple. 

 There are two varieties, S. H. altissima and S. H. elatior, both good.
