Europe. A large tree of this umbrella pine twenty 

 feet high, as it can be seen in Europe, is a fine sight. 

 It is quite hardy. 



The Thuyas (arbor-vitas) are most of them hardy, 

 compact, and of pyramidal form. Their colouring is not 

 as fine as the biotas, but they are hardier. Most of 

 them are varieties of the American arbor- vitas. There 

 is a Thuya standishii, that is hardy and graceful with 

 slightly pendulous branches. The Retinosporas are a 

 beautiful family, but some of the kinds fall into a bad 

 condition unless they are frequently pruned. This ap- 

 plies to the Retinospora plumosa, squarrosa and psifera; 

 Retinospora obtusa and filifera are better. There is 

 also a weeping hemlock (Sargent's weeping hemlock) 

 which should have been noted before as a very beautiful 

 evergreen, and also Tsuga sieboldii, a hemlock of very 

 deep green colour, compact and hardy and a good tree 

 though seldom seen on lawns. It should be understood 

 that the term hardiness is meant in all cases to apply 

 to the Middle States of the United States. 



These notes are closed with the evergreens. Peren- 

 nials and bedding plants of the tender kinds are too 

 extended a subject to properly discuss within the limited 

 space of this book. Moreover, such plants as the 

 irises, phloxes, larkspurs, pinks, hollyhocks, peonies, 

 the bedding plants, cannas, salvias, geraniums, and 

 coleuses fill up the minor spaces of the landscape picture. 

 They have great beauty, perhaps as much as anything 

 on the lawn, but they do not count much in the general 

 survey of the picture. It would not be unpleasant or
