ROSES AND LILIES 83 



quence of colour in a large border of hardy flowers, 

 namely, in a gradual progression of colour-harmony in 

 the case of the red and yellow flowers, whose numbers 

 preponderate among those we have to choose from ; 

 but saying that as far as my own understanding of 

 the colour-requu-ements of flowers went, it was better 

 to treat blues with contrasts rather than with har-

 from a little distance, I could see in company the

 with the brilliant blue of some full-blue Delphiniums, 

 how splendid, although audacious, the mixture was, 

 and immediately noted it, so as to take full advan-

 In the autumn, two of the large patches of Lilies 

 were therefore taken up and grouped in front of, and 

 partly among, the Delphiniums ; and even though 

 neither had come to anything like full strength in 

 the past summer (the first year after removal), yet 

 I could see abeady how grandly they went together, 

 and how well worth doing and recommending such 

 a mixture was. The Delphiniums should be of a

 my garden, the large variety " splendens " being the

 at least every three years. By a poorer and smaller 

 growth and an earlier yellowing of leaf, they show
