in the suggested combinations. I can only repeat what I say 
elsewhere, that white and green are the best possible foils for 
colored flowers, and are indispensable in a garden that ex- 
presses delicacy and grace. 
There are many plants whose manner of growth does not 
lend them easily to general combinations, although the color 
may be harmonious; for example: the German iris throws out 
a heavy root stock in a circular way, which soon makes an un- 
manageable clump; and if divided, to keep it small, it takes a 
year, or more, according to the division, for it to bloom again. 
Also the Incarvillea Delavayi is surrounded by large radical 
leaves that are so admirably adapted as a background for its 
tall flower stalks that it needs no other plant as a foil. The 
same is true of Archangelica with its great acanthus leaves,
