5 8 THE BOOK OF CLIMBING PLANTS 



Lippia citriodora, known as Aloysia citriodora or 

 Verbena triphylla to many gardeners, is hardy only on a 

 wall, and even thus protected is too tender for cold 

 places. Its popular name of the Sweet Verbena gives 

 an idea both of the character of its whitish flowers and 

 of the fragrance of the plant, best observed when the 

 leaves are bruised. In the favoured south-west of 

 England and in some other congenial districts some of 

 the Myrtles may be cultivated against a wall, where 

 their beauty and sweetness are appreciated. Myrtus 

 communis, the common Myrtle, is charming in such 

 places with its white flowers. There are a good 

 many varieties in cultivation, all being propagated by 

 cuttings of partially ripe wood under a glass. M. 

 Ugni, perhaps better known as Eugenia Ugni, is also 

 a pretty shrub, with white flowers succeeded by 

 pleasing, pleasantly flavoured red or black berries. It is 

 hardy in similar positions and places as suits M. com- 

 munis. Upon the whole, the wall is the best place for 

 the charming Olearias in many places. The prettiest of 

 those which need such protection is O. stellulata, 

 covered with a profusion of white, Daisy-like blooms. 

 It has greyish foliage. O. Haastii is hardier and is a 

 handsome species, which looks well against a wall or in 

 the open. The olearias like a rather light soil, and are 

 easily propagated by cuttings in spring or summer, taken 

 with a heel. 



For growing against a wall some of the Philadelphuses, 

 the Mock Oranges or Syringas, are very effective with 

 their pretty flowers. A list of the taller-growing 

 species appears in the tables, but it may be said that P. 

 grandiflorus is one of the most suitable. These flower 

 on the wood of the previous year, so that this should be 

 well cut away after blooming and the young shoots laid 

 in. They are propagated by layers, suckers, or by 

 cuttings of the young growths under a glass. The
