will do well in any kind of soil if it is not too wet in winter. Peonies 

 are amongst the most beautiful of hardy plants and play a very 

 important part in the summer garden. There are so many varie- 

 ties that it is hard to say which is the best; it is very much a matter 

 of taste. After they are done flowering the beds look unattractive 

 but there are several kinds of lilies which do well amongst them 

 and produce flowers for the remaining part of the summer. 



The showiest plants of July are Japanese irises; they are not 

 hard to grow if they are given damp soil which is well enriched. 

 They dislike shade and do as well on the margin of a pond as any- 

 where. There is an endless variety of colors, many of them per- 

 fectly beautiful. 



A garden would not be complete without a collection of perennial 

 phloxes and perhaps they are the most useful of all hardy plants. 

 We have them in blossom from April until September. There is 

 an endless variety of colors and it is only a matter of taste which are 

 the best kinds. They like rich soil and plenty of water; young 

 plants give the largest trusses of flowers. 



There are so many kinds of plants that blossom in the summer 

 that I have no time to describe them, but the following kinds 

 should be grown for the summer display: Achillea, Aconitum, 

 Alstroemeria, Anchusa, Anthemis, Anthericum, Bocconia, Cam- 

 panulas, Chrysanthemum, maxirmmi, Dianthus, Er;^mgiums, Fun- 

 kias, Gaillardias, Geum, Gypsophila, Day lilies, Lathyrus, Mon- 

 arda, Pyrethrums, Rudbeckias, Scabious, Spiraeas, Thalictrums, 

 Verbascum, and Veronicas. 



Roses are the most important shrubs that blossom during the 

 summer. The Hybrid Perpetuals or the old garden roses are 

 going to be displaced by the Tea and Hybrid Tea roses. Instead 

 of blossoming for only a few weeks as the Hybrid Perpetuals do 

 the Tea will produce flowers all summer. Rhododendrons and 

 Kalmia are useful for their gorgeous blossoms. Vitex incisa is 

 showy in July when there are very few shrubs in blossom. The 

 different species of Philadelphus are especially useful for white 

 effects and they are easy to grow. Spiraeas, Viburnums, Hydran- 

 geas, and Deutzias are the most important shrubs. 



The autumn garden should begin in August and continue to 

 the end of October, although if the weather is mild there will be
