This tree has a rapid growth and its shape well adapts it for street and 

 garden planting. It is not particular about quality of soil, but needs a moderate 

 amount of moisture. At present it is quite rare, but its many good qualities 

 make it deserve more extensive planting. Under favorable conditions it 

 attains a height of about fifty feet. It cannot stand much frost, however, 

 which does not recommend it for the interior valleys. 



JACARANDA 



The jacaranda (Jacaranda ovalifolia) is a native of Brazil which does 

 well in subtropical regions. It reaches a height of about fifty feet and com- 

 mands attention in the early summer by its profusion of large blue panicles 

 of bignonia-like flowers and finely cut fern-like foliage. The shape of the 

 tree is apt to be straggling unless it is carefully pruned. 



This tree is used on the streets of Santa Barbara and Pasadena with good 

 effect. It is too tender for regions of severe frost, and thrives best in warmer 

 situations sheltered from strong winds. 



JERUSALEM THORN 



The Jerusalem thorn (Parkinsonia aculeata) takes its generic name 

 after John Parkinson, an English botanical author and herbalist to James I. 

 It grows naturally in Texas, Arizona and Mexico and is cultivated in many 

 warm countries as an ornamental small tree and to form hedges. 



It is a thorny evergreen tree with feathery drooping branches and fra- 

 grant yellow flowers borne on racemes. It reaches a height of about fifteen 

 feet under cultivation, the pendulous branches forming a wide, graceful 

 head. The pods, commonly known as horse beans, which are constricted 

 between the seeds, hang in graceful racemes from the tree. 



This tree, which belongs to the same tribe as the honey locust, will thrive 

 in the driest soil and can endure considerable cold. 



EUROPEAN LAUREL 



The European laurel, commonly known as the sweet bay, was regarded 

 by ancient peoples as an emblem of truth and it was forbidden to put it to 

 any profane use. It was a favorite tree of poets and scholars, and graduates
