WHAT TO PLANT IN EASTERN CANADA 



SUGAR or ROCK MAPLE 

 NORWAY MAPLE 

 RED MAPLE 



AMERICAN ELM 



RED OAK 



MAIDEN HAIR TREE 



WHAT TO PLANT IN PRAIRIE PROVINCES 



MANITOBA MAPLE 

 RUSSIAN POPLAR 

 BALSAM POPLAR 

 GREEN ASH 



ALSO IN SOUTH MANITOBA: 

 ELM and BASSWOOD

2. Straightness and symmetry. One de- 

 crepit tree on a street may mar the whole 

 effect. 



3. Freedom from the attacks of insects and 

 fungous diseases. 



4. Good foliage habits to give abundance of 

 shade. 



5. Cleanliness in habit of growth during 

 flowering and fruiting stages. 



6. Longevity. Street trees must not be 

 short-lived or easily broken by winds. 



Six Good Trees for Eastern Provinces 



In the eastern provmces of Canada the six 

 trees described later on are at the top of the list 

 for street planting. In the prairie provinces 

 these trees are not hardy, consequently certain 

 varieties which we look upon as too inferior for 

 planting in eastern cities have to be used. The 

 best of these are (I) the Manitoba Maple, (2) 

 the Russian Poplar, and the Balsam Poplar, (3) 

 the Green Ash. In the southern parts of Man- 

 itoba the Elm and Basswood succeed fairly well.- 

 The Canoe Birch and the native Cottonwood are 

 also varieties which succeed well. 



Sugar or Rock Maple (Acer saccharum). — ^A 

 well known native tree, rather large, shady and 

 upright in form. It thrives in most soils, ex- 

 cept those of a heavy clay type. It makes a 

 magnificent street tree, and one which is not 

 troubled in Canada to any extent with fungous 

 diseases, and does not require much pruning. 

 In the autumn the leaves turn to brilliant shades 

 of scarlet, orange and yellow. It has been 

 found that it does not thrive in some American 

 cities so well as the Norway Maple, as its foliage 

 is sensitive to dust and smoke. This is the tree 

 from which maple sugar is principally made. 



Norway Maple (Acer platanoides). — This 

 maple is a native of Europe. It is a fairly large 

 and handsome tree with a compact, round 

 head, not quite so large as our native maples. 

 It is quite hardy in Canada, and is frequently 

 used as a street tree. In the spring, the bright 

 greenish, yellow flowers which come out with 

 the bursting of the buds makes the tree a con- 

 spicuous object. The leaves are rather larger 

 and darker than those of the native maples. 

 In the autumn, it colors yellow and makes a 

 pleasing contrast to the red and sugar maples. 



It is a tree which is very easily transplanted and 

 and for this reason it is very much used for a 

 street tree in many cities on this continent. 



Red Maple (Acer rubrum). — Although not 

 quite so desirable a street tree as the Rock 

 Mc.ple, it is a tree of upright form, with a com- 

 paratively narrow round head. !t is also a 

 native of Canada and has most of the good 

 points of the maples. It is very conspicuous 

 in early spring on account of its bright scarlet 

 flowers, which come out before the leaves. 



American Elm (Ulmus americana). — A large 

 handsome tree particularly adapted for wide 

 streets or avenues. It combines size and 

 strength with beauty and grace of form, per- 

 haps more than any other tree. It is one of the 

 most rapid growing of all trees, will stand ad- 

 verse conditions fairly well, and does well in 

 many types of soil. No other tree in the 

 whole list stands out so conspicuously as an 

 all-round useful tree for street and avenue plant- 

 ing. Unfortunately, however, it is in some 

 parts frequently troubled by insect enemies. 



Red Oak (Quercus rubra). — The oaks are not 

 so extensively planted as street and avenue
