USE OF HARDY CLIMBING SHRUBS 303 



PiPTANTHUS NEPALENSIS (Nepaul Laburnum). — 

 This is a shrubby wall plant, and not a very im- 

 portant one. Its yellow flowers remind one of those 

 of the Laburnum, and are borne in clusters. 



Polygonum baldschuanicum. — A beautiful 

 shrubby climber, with clouds of white, pink-tinted 

 flowers in summer and autumn. An illustration 

 shows it clambering into a Fir tree near the rock 

 garden at Kew. I have seen many poor forms in 

 gardens, seedlings, and therefore to keep the true 

 type, it must be increased by cuttings. If frost cuts 

 the stems down in winter, new growths spring up in 

 the following year. Its graceful flower masses are 

 useful in the house. P. molle is not unlike it, but 

 there is considerable difiference between them. 



PUNICA. 



Pyrus. — ^The Pyruses are described elsewhere in 

 this book. P. {Cydonia) japonica and its many beautiful 

 varieties and P. Maulei are, however, more frequently 

 grown against walls than any other members of the 

 same family. Pruntts triloba is an excellent wall shrub. 



Rosa (Rose). 



RUBUS. 



Smilax. — This group is not common in gardens, 

 but is interesting. They are a change from the 

 repetition of a few common things. S. rotundifolia 

 is a very handsome large-leaved Smilax with shiny 

 foliage, now and then met with as S. laurifolia or S. 

 latifolia, from which, however, according to Mr. R. 

 Irwin Lynch, of Cambridge, it is distinct. All the 

 kinds of hardy Smilax form handsome leafy creepers
