G. rivale Guildford variety, 1 foot high, has 

 salmon-pink flowers ; G. montanum, golden 

 yellow, and var. aurantiacum, orange-yellow, 

 are rock garden plants, about 9 inches high. 



Gypsophila 

 (Chalk Plant). 

 The popular name 

 of Chalk Plant is 

 presumably derived 

 from the fact that 

 the plants delight 

 in a soil containing 

 chalk or lime. 

 Individually the 

 tlourrs are small, 

 but they are pro- 

 duced in lavish 

 abundance on thin, 

 wiry stems. When 

 in bloom large 

 plants of Gypsophila 

 paniculata resemble 

 a mound of snow 

 some 3 or 4 feet 

 high. The flowers 

 are highly prized 

 for cutting, not so 

 much for their effect 

 alone, but because 

 the long elegant 

 stems and small 

 white flowers har- 

 monise so well with 

 brightly coloured 

 flowers in vases and 

 bouquets. The 

 Gyp HO phi las are 

 very effective in

 herbaceous bolder, 

 also in beds on the 

 lawn ; they form a 

 useful groundwork 

 for some of the 

 taller-growing Lilies 

 and the large- 

 flowered Gladioli. 



Plant them in a sunny spot and in well- 

 drained loamy soil, in which old manure 

 and mortar rubble have been mixed. 

 Autumn and spring are suitable planting 

 oonoono. Division of the roots is best done 

 in March, and cuttings should be inserted 



during April and May. The double variety 

 does not root readily from cuttings ; the 

 best method of propagating tin's plant is to 

 graft it on pieces of the root of the single

kind in spring. Seeds also form a ready 

 moans of propagating the single-flowered 

 kinds ; they are sown in late summer 

 or in spring. The best known are G. 

 paniculata, 2 to 3 feet high, producing a 

 cloud of white flowers from July to Sep-
