THE ROMANCE OF OUR TREES 



Spruces, Firs, Hemlocks, and Yews supply nearly 

 all the decorative dwarf forms of tree-growth our 

 gardens possess. 



One of the best known and most widely used of 

 these dwarf evergreens is the Mugho Pine (Pinus 

 montana, better known as P. mughus or P. pumilio). 

 This is a native of the mountains of central and 

 southern Europe. On the Pyrenees it occurs both as 

 a shrub and as a tree of moderate size; on the Tyrolese 

 Alps it is everywhere a low, densely branched bush. 

 In cultivation it is a broad shrub with many erect 

 stems, occasionally reaching the height of 15 feet, 

 and covered with dark green leaves. 



On the higher mountains of eastern Asia and north- 

 ern Japan, and reaching sea-level in Saghalien, grows 

 Pinus pumila, in many ways the counterpart of the 

 Mugho but belonging to another section of the genus. 

 This oriental dwarf Pine is creeping in habit and 

 forms an impenetrable tangle from less than a yard to 

 fully 10 feet in height. Unfortunately it has not 

 taken kindly to cultivation — yet why it should be 

 intractable is unexplainable. 



Of the noble White Pine of eastern North America 

 (P. Strobus) there are several dwarf forms of pleasing 

 appearance. The best is var. nana, a compact, bushy 

 shrub with short, slender branches and numerous 

 branchlets clothed with short leaves that are densely
