Karri, Eucalyptus diversicolor, and the Jarrali, Eucalyptus marginata, 

 thrive well in cultivation, as also does that fine tree, the Brisbane 

 Stringybark, Eucalyptus siderophloia. Another very ornamental tree 

 is the Blood wood, Eucalyptus corymhosa. Indeed, it may be said that 

 any of the eucalypts will succeed as a cultivated plant. 



The gum tree most popularly grown, especially for shade, is 

 Eucalyptus corynocalyx ( cladocalyx) , the Sugar Gum. It is a quick 

 grower, and apt to grow tall, leaving the lower growths unfurnished. 

 In Horsliani, Victoria, there are magnificent avenues of sugar gums

planted as street trees. The sugar gum has very brittle wood, and the 

 long sprawling limbs often snap off under stress of a wind storm. It 

 is also subject to the boring larvae of certain beetles and moths. 



Eucalypts may all be trimmed or pruned into shape. Indeed, 

 many of the quick-growing ones, like the sugar gum, may be cut hard 

 back to the trunk, leaving only the bare stem standing. The pruning 

 should be done in early spring, so that the subsequent tender growths will 

 not be injiired or burned by frost.
