THE ORNAMENTAL PLANTS — TREES 



319 



The climbing polyantha roses (hybrids of Rosa multiflora 

 and other species) include the class of ''rambler" roses that has 

 now come to be large, including not only the Crimson Ram- 

 bler, but forms of other colors, single and semi-double, and 

 various chmbing habits; a very valuable and hardy class of 

 roses, particularly for trellises. 



The Memorial rose {R. Wichuraiana) is a trailing, half-ever- 

 green, white-flowered species, very useful for covering banks and 

 rocks. Derivatives of this species of many kinds are now avail- 

 able, and are valuable. 



The Ayrshire roses (R. arvensis var. capreolata) are profuse 

 but rather slender growers, hardy North, bearing double white 

 or pink flowers. 



The Cherokee rose {R. Icevigata or R. Sinica) is extensively 

 naturalized in the South, and much prized for its large white 

 bloom and shining foliage; not hardy in the North. 



The Banksia rose {R. Banksice) is a strong chmbirg rose for 

 the South and California with yellow or white ^owers in 

 clusters. A larger-flowered form (R. Fortuneana) is a hybrid of 

 this and the Cherokee rose. 



The climbing tea and noisette roses, forms of R. Chinensis and 

 R. Noisettiana, are useful in the open in the South. 



7. Trees for Lawns and Streets 



A single tree may give character to an entire home property; 

 and a place of any size that does not have at least one good tree 

 usually lacks any dominating landscape note. 



Likewise, a street that is devoid of good trees cannot be the 

 best residential section ; and a park that lacks well-grown trees 

 is either immature or barren. 



Although the list of good and hardy lawn and street trees is 

 rather extensive, the number of kinds generally planted and 

 recognized is small. Since most home places can have but few 

 trees, and since they require so many years to mature, it is
