MANUAL OF GARDENING 



Bougainvillea, Bougainvillma glabra and B. spectabilis. 



The magenta-flowered variety, sometimes seen in conservatories in the 

 North, is a popular outdoor vine in the South and is profusely used in south- 

 ern California. The red-flowered form is less seen, but is preferable in color. 



Wire- vine (polygonum of florists), Muehlenheckia complexa. 



Abundantly used on buildings and chimneys in southern California. 



Climbing roses. 



The roses do not twine nor possess any special climbing organs; 



therefore they must be provided with a. trellis or woven-wire 



fence. Some of the 

 roses classed as climb- 

 ing are such as only 

 need good support, Fig. 

 267. For culture of 

 roses,seeChapterVIII. 

 The most popular 

 climbing or pillar rose 

 at present is Crimson 

 Rambler, but while it 

 makes a great display 

 of flowers, it is not 

 the best climbing rose. 

 Probably the best of 

 the real climbing roses 

 for this country, 

 bloom, foliage, and 

 habit all considered, 

 are the derivatives of 

 the native prairie rose, 

 Rosa setigera (native 

 as far north as On- 

 tario and Wisconsin). 



Baltimore Belle and Queen of the Prairie belong to this class.
