USE OF HARDY CLIMBING SHRUBS 319 



OLEARIA (see p. 405). 



PASSIFLORA C/ERULEA. Few climbing plants are 

 more fascinating than the blue Passion Flower. It 

 is, with its bluish flowers and orange, egg-shaped 

 fruit, most happy against a warm wall, and is not the 

 hardiest of climbers. The white variety, Constance 

 Elliot, should be grown also. 



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. 



PRUNUS TRILOBA is an excellent wall shrub (see 

 illustration). 



PUNICA (Pomegranate). Both single and double. 



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. Prunus triloba is an excellent wall shrub, 



RAPHIOLEPIS OVATA. A very handsome plant. 



ROSA (Rose) (see p. 342).
