This tree ma}^ be used as a hedge plant, as a shrub for the 

 lawn or garden, as a specimen tree for large grounds, or as a 

 street tree, and is perhaps the best of the whole list for general 

 planting. The habit is dignified, yet graceful and pleasing. 

 Its leaves are plentiful, clean, glossy, and green. It prunes 

 well, and so may be molded to harmonize with its surroundings. 

 Eugenia is hardy for all of the coast district of California, 

 grows well as far north as Sacramento (and there is no reason 

 why it should not be used much beyond this latitude), and in 

 the interior at least as far as Redlands. 



When it is desired to form a tall, narrow hedge, the plants 

 should be set close together. If a shrub is desired, the growth 

 of several central stems should be encouraged and the head cut 

 back. Even so it will insist on becoming a tree in favorable 

 localities, in which case it will be necessary to resort to root 

 pruning. 



Growth is not rapid, although one specimen at Coronado 

 attained a height of 40 feet in 20 years. At Santa Barbara 

 a tree 80 feet high was observed, but the age is not known. 

 On the San Francisco Peninsula it is commonly grown in 

 masses and therefore remains low. A good example, 20 feet 

 high, may be seen on the Capitol grounds at Sacramento. 



As a street tree, Eugenia myrtifolia would almost certainly 

 be a splendid success. The difficulty of procuring a large 

 supply of trees has prevented its use for this purpose, but they 

 are now sufficiently plentiful to warrant its adoption for some 

 of our more progressive cities. 



Propagation is easily accomplished from seeds, but these 

 are not to be had in large quantities. Cuttings taken from 

 firm or partially ripened wood strike without difficulty.
