192 THE ENGLISH FLOWER GARDEN. 



be American Azaleas, Wallflowers, German and Spanish Iris, Alpine 

 Auriculas, Polyanthus, and Alstrcemerias. 



It is important to notice that the mass of each colour should be 



large enough to have a certain dignity, but never so large as to be 



wearisome ; a certain breadth in the masses is also 



Breadth of mass wanted to counteract the effect of foreshortening 



and when the border is seen from end to end. When a 



intergrouping. definite plan of colouring is decided on, it will 

 save trouble if the plants whose flowers are ap- 

 proximately the same in colour are grouped together to follow 

 each other in season of blooming. Thus, in a part of the border 

 assigned to red, Oriental Poppies might be planted among or next 

 to Tritomas, with scarlet Gladioli between both, so that there 

 should be a succession of scarlet flowers, the places occupied by the 

 Gladioli being filled previously with red Wallflowers. 



Warm colours are not difficult to place : scarlet, crimson, 

 pink, orange, yellow, and warm white are easily arranged so as to 

 pass agreeably from one to the other. Purple and lilac group well 

 together, but are best kept well away from red and pink ; they do 

 well with the colder whites, and are seen at their best when sur- 

 rounded and carpeted with grey-white foliage, like Cerastium tomen- 

 tosum and Cineraria maritima ; but if it be desired to pass from 

 a group of warm colour to purple and lilac, a good breadth of pale 

 yellow or warm white may be interposed. 



Care must be taken in placing very cold white flowers, such as 

 Iberis correaefolia, which are best used as quite a high light, led up 

 to by whites of a softer character. Frequent repetitions of white 

 patches catch the eye unpleasantly ; it will generally be found that 

 one mass or group of white will be enough in any piece of border 

 or garden arrangement that can be seen from any one point of view. 



Blue requires rather special treatment, and is best approached 

 by delicate contrasts of warm whites and pale yellows, such as the 

 colours of double Meadow Sweet, and QEnothera Lamarckiana, but 

 rather avoiding the direct opposition of strong blue and full yellow. 

 Blue flowers are also very beautiful when completely isolated and seen 

 alone among rich dark foliage. 



In a mixed border they might begin with strong blues, light and 



dark, grouped with white and pale yellow, passing on to pink ; then 



to rose colour, crimson, and the strongest scarlet, 



A progression leading to orange and bright yellow. A paler 



of colour. yellow followed by white would distantly connect 



the warm colours with the lilacs and purples, and a 



colder white would combine them pleasantly with low-growing 



plants with cool-coloured leaves.
