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 climbing 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. levigata 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. Banksie) is a strong climbing rose for 
the South and California with yellow or white flowers in 
clusters. A larger-flowered form (Rf. 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
