SII/BNE 



little mortar rubbish ift half-shady places 

 in the rook garden. When it finds a favour- 

 able spot it reproduces itself readily from 

 self-sown seed. 



S. quadridetitata. — A Species closely 

 related to S. alpestris. It grows 4-6 in. 

 high, and forms dense masses of green 

 linear oblanceolate leaves about i| in. 

 long. The flowers are fteely produced in 

 summer — from June oawards — in loose 

 panicles, and are pure white with wedge- 

 shaped 4-toothed petals. 



Cultufe Sc. as above for S. acautis. 



S. quadrifida. — ^A pretty loose-growing 

 European species somewhat resembling 

 Gypsophila elega/ns in appearance. It 

 grows 3-6 in. high, its slender stems being 

 furnished with linear leaves about 1^ in. 

 long. The white wedge-shaped flowers 

 with 4 blunt teeth appear from June 

 onwards in great profusion and are very 

 attractive. 



Culture Sc. as above for S. acaulis. 



S. regia (Boyal Oatchfiy). — A downy 

 pereimial 3-4 ft. high, native of the S. 

 United States. Leaves thiokish, ovate 

 lance-shaped, acute. Flowers in summer, 

 deep scarlet, numerous, in clusters ; petals 

 spoon-shaped, lanceolate, mostly un- 

 divided. 



Culture dc. as above for S. acaulis. 

 Increased by seeds or division. Should 

 be grown in a warln corner of the flower 

 border. 



S. Saxifraga. — A smooth, rather 

 clammy tufted perennial, 3-6 in. high, 

 native of the Alps, with acute linear leaves. 

 Flowers from June to August, yellowish- 

 white above, reddish beneath, and usually 

 borne singly on very long stalks, but oc- 

 casionally two or three on the same stem. 



Culture amd Propagation. — Owing 

 to the thickness of its light green leaves 

 this species is excellent for making a 

 carpet under taller plants in the rockery 

 or border, especially as it likes a certain 

 amount of shade, but plenty of ventilation, 

 and a light and rather sandy soil with a 

 little leaf mould or peat. 



Seeds may be sown as soon as ripe in 

 the open border, and the young plants 

 may be moved to their flowering positions 

 before the end of September, Or in mild 

 weather the following spiring. In cOld 

 northern parts, it is safes' to sow in 

 autumn in cold frames and plant out in 

 spring. Seeds however may also be sown 



out of doors in April and May for later 

 blooming. The plants may also be divided 

 when they have made good tufts in spiring 

 or ettrly autumn, the distance between the 

 replanted portions being 9 to 12 iflches. 



S. Schafta. — A pretty Caucasian peren- 

 nial rarely exceeding 6 in. high. Leaves 

 obovate, acute. Flowers from .Tune to 

 October, purple, erect, gradually covering 

 the stems ; calyx club-shaped, nlore than 

 1 in. long; petals wedge-shaped, sHiaU 

 toothed. 



Culture Sc. as above for 8. Saxifraga. 

 hike the latter species 8, Schafta is ad- 

 mirably suited for carpeting patches in 

 the rock garden or border. 



S. ^iipina. — A tufted Caucasian peren- 

 nial, with downy, clammy, woody stems. 

 Leaves linear, acute. Flowers from June 

 to August, white, on short alternate 

 stalks ; calyx long, cylindrically club- 

 shaped, woolly ; petals long-clawed, cleft. 



Culture dec. as above for S. acauUs. 



S. vespertina. — A beautiful downy 

 annual 1 ft. high, native of Greece. 

 Leaves spoon-shaped, acute, on ciliated 

 stalks. Flowers in smnmer, rosy, all 

 turned on one side of the raceme ; calyx 

 bladdery, club-shaped ; petals 2-lobed. 



Culture d-c. as above for S. compacta, 

 or S. pendula. Increased by seeds. 



S. virginica {Fi/re Pirik). — A downy 

 perennial 1-2 ft. high, native of North 

 America. Leaves thin, spoon-shaped, or 

 the upper ones oblong, lance- shaped. 

 Flowers in summer, 2 in. across, deep 

 crimson, few and loosely cymose ; calyx 

 oblong cylindrical, becoming obconi- 

 oal ; petals oblong, 2-cleft. 



Culture and, Propagation. — This 

 species is best raised from seeds, as it 

 takes a long time to recover if divided. 

 It should have a particularly well- drained 

 position in the rockery or border, as 

 wetness at the root in winter is more or 

 less injurious to it. 



S. ZaTit^adski. — A pretty Galician per- 

 ennial with, rosettes of radical lance- 

 shaped acute leaves, and slender erect 

 flower stems 6-8 in. high, bearing forked 

 clusters of white flowers from May to 

 July. The roilndish petals are furnished 

 with 2 linear scales at the base. 



Culture and Propagation. — Thi.'! 

 species requires the same treatment in 

 every way as S. Saxifraga and S. Schafta, 

 above.
