Marguerite, as it is often called) is extensively grown in 

 beds and borders, and is also valuable for cut flowers. It 

 attains a height of 2ft., producing its purple and white flowers 

 during August. Numerous varieties of it are now in cultivation, 

 one of the best being Burridgemiwn (Fig. 116), a compact- 

 growing plant, bearing white or yellow flowers, with crimson 

 or purplish-brown rings, enclosing a purple disk, and growing 

 to a height of i8in. ; Lord Beaconsfield, a form with mauve 

 and yellow flowers growing 2ft. high, is also very good. There 

 are numerous others, some with large handsome double flowers 

 of many beautiful shades ; others with double fringed flowers in 

 white, rose, orange, scarlet, crimson, c^c. ; others, again, with 

 bright single flowers ; whilst a further section have golden leaves. 

 These will be noted in the " Appendix." 



C. coronariuni (Crown Daisy) is a useful border-plant, 

 thriving well under the influence of smoke. It is, therefore, a 

 favourite in town gardens, growing to a height of 22ft., and 

 flowering continuously from July to September. The typical 

 flower is yellow, but under cultivation, and in the hands of the 

 hybridist, several forms have originated, so that we now have 

 varieties with double yellow, white, and lemon flowers. It is 

 best sown in April or early in May. C segetiini (Corn Marigold), 

 although a British plant, is worthy of a position in the flower- 

 border. It grows to a height of i8in., and produces its yellow 

 flowers from June to August. The variety grandiflorum is a 

 first-rate border-plant, growing 2ft. high, and bearing very large 

 rich yellow flowers, which are greatly valued for cutting. 



Clarkias are free-flowering border plants, of light, graceful 

 habit, and very easy of culture. The seed may be sown outside in 

 September, either in permanent positions or in beds for trans- 

 planting into the open border as soon as large enough ; these 

 will flower well in the early spring. The first sowing in spring 

 should take place in March, thinning the plants to about Qin. apart ; 

 these will flower in July, when the autumn-sown plants are past 

 their best. Other sowings for succession should be made until 

 about the beginning of June, these keeping up a supply of flowers 

 until the end of October. Clarkia elegans is an erect-growing 

 much-branched annual, 2ft. high, bearing numerous purple or 

 rose-coloured flowers on long leafy racemes. There are now many 

 forms of this species, with different coloured flowers. These 

 form strong branching plants, very profuse flowering, and are 

 very effective subjects when grown as border plants; they are also 

 extremely useful when grown in beds by themselves — whether the 

 kinds are kept separate or mixed. The variety Tom Thumb, with 

 rose-coloured flowers, grows only ift. high, and is an excellent 

 plant for sunny spots in the rockery, or in the front of the 

 herbaceous border. C. pulchella growls 2ft. in height, producing 

 its flowers in June ; it is easily distinguished from C. elegans by
