TREES, SHRUBS, AND VINES 



SUITABLE FOR CALIFORNIA SCHOOL GROUNDS. 



By DR. HARVEY HALL, of the University of California. 



TREES 



ACACIAS are eminently adapted to school grounds; rapid growers not 

 particular as to soil, hardy, easily cared for. Of the feathery-leaved 

 sorts Acacia mollissima is perhaps the best and develops into a larger 

 shade tree with an abundance of yellow flowers in early spring. A. 

 melanoxylon, a broad-leaved species, has a more dense foliage and is 

 of rather somber aspect. A. bailey ana is very handsome as a lawn 

 tree ; growth erect, foliage silvery-white. 



ALBIZZIA is often mistaken for Acacia, which it resembles, but it is 

 even more rapid in its growth, endures considerable drought, and has 

 larger compound leaves. 



AUSTRALIAN BUSH-CHERRY is a most dignified evergreen tree, carry- 

 ing its head high, but with gracefully drooping sprays of rather small 

 glossy-green leaves. The edible fruits may be objectionable in a tree 

 for school yards. 



CAMPHOR trees are suitable for districts of little or no frost. It will 

 furnish material for demonstrating the commercial preparation of 

 camphor. 



COTTONWOODS are large deciduous trees suitable for playgrounds 

 where shade during the summer months is desired. Best grown on low 

 ground where the subsoil is moist. Easy and rapid. 



LINDENS are among the most hospitable of all, their whole aspect 

 being one of welcome. The generously broad leaves furnish abundant 

 shade except in winter. Hardy and easily grown. White and Silver 

 Linden is the best. 



MAPLES are well known. Where a large tree is needed our native 

 Broad-leaved Maple should be used. The Silver Maple is somewhat less 

 spreading but more handsome. 



MAYTEN "Smilax Tree," the slender parent twigs and small oval 

 leaves, simulating sprays of smilax. A slow-grower, eventually forming 

 a tall tree. Evergreen and perfectly hardy. 



OAKS are slow growers, but a few should be planted, where possible, 

 as a legacy for future generations. The native evergreen Field Oak, or 

 Encina, is one of the best for shade purposes. 



PEPPER trees are always satisfactory. Care should be taken in plant- 

 ing to see that only staminate trees are used, since the berries of pistillate 

 trees cause objectionable litter.
