 The Walnuts. 



The Walnuts (Juglans sg. ) of various species and horticultural kinds are 

 all frequently found in the parkings. Often they are the remnant of some old 

 orchard but more frequently they are the deliberate choice of the owner who 

 desires to derive not only shade but profit from his trees. If we consider the 

 sprawling form of young walnuts which have the frequent waterings of the parking 

 and the fact that they attain great size, and furthermore, that they, or their 

 insect visitors exude a gummy substance which makes the pavement very unsightly 

 for at least two months of the year, - if we consider these things, we can see 

 that tiie walnut is certainly not desirable for narrow streets and if useful at 

 all, is best suited to broad highways on the edge of town. Here it may develop 

 to its greatest perfection and will not interfere in any way. Many of the 

 native walnuts appear as magnificent specimens, which deserve great admiration. 

 But an immense specimen may not always look well when it is put in the artificial 

 conditions of the parking. 



The Jscaranda. 



The Jacaranda (Jacaranda miraisaefolia)is an ornamental tree attaining per- 

 fection only in the coast cities of tne south, where the frost is not severe. 

 It bears large and delicate pinnate leaves and good sized panicles of showy 

 purple flowers in July and August. The growth of the plant is inclined to be 

 somewhat straggling and an occasional corrective pruning may be necessnry. 

 Too heavy or too frequent pruning will have the same effect as heavy frosts, 

 namely of removing the new wood which will produce the flowers for the following 

 season. 



Cv/ing to its small size, this tree is suitable only for narrow streets or 

 for elternetion with more rank growing species, which will provide sufficient 

 shade. As it has a tendency to form many leaders quite early in life, nursery 

 stock should be selected with care and watched that the frost or other agencies 

 do not kill the leader before it has reached a sufficient height.
