There are many shrubs which are either so decorative 

 or come to greater perfection on walls or treated as 

 climbers against trellises and on the pillars of pergolas, 

 that they must have a due amount of attention here. 

 For low walls one of the most attractive genera is the 

 Ceanothus, which gives us a great many species, varie- 

 ties and hybrids. Among these there is hardly one 

 which will not repay the little care it requires, and 

 which will not by its beauty make the cultivator con- 

 gratulate himself upon giving it the needed space. 

 The greater number of the forms have blue or 

 bluish flowers, but there are some with white 

 blooms. It is when we come among some of the 

 hybrids or varieties which approach red in their colour- 

 ing that we seem to enter the least hardy section, but 

 we may take it that the varieties of azureus are hardy 

 in most places, while americanus, the New Jersey Tea, 

 is even hardier, with its bluish or white flowers. They 

 all like a rather light soil, though not fastidious in this 

 respect, and good drainage. They are propagated by 

 layers or by autumn-struck cuttings in a frame in light 

 soil. They require to be neatly fastened to a wall, and
