LIST OF ORNAMENTAL SHRUBS AND TREES SUITABLE FOR PLANTING 

 IN DIFFERENT REGIONS OF THE UNITED STATES 



For permanent effects in ornamental planting woody plants, both 

 deciduous and evergreen should be used. Their effect is continuous from 

 year to year, and winter as well as summer decoration can be provided. 

 Plants native to any section should be given first consideration. These 

 may be observed in the woods and fields in summer and transplanted at 

 the next appropriate transplanting season. Next in value are those sug- 

 gested in the following lists. Many of these plants are also native. Orna- 

 mental plants for use in the different regions shown on the regional map 

 (Plate 254, page 674) are arranged in the following list according to their 

 approximate ultimate height. This height will vary much, according to the 

 region where grown, to the character, tilth, fertility, moisture content and 

 acidity of the soil, the exposure and the care the plants receive. 



Those plants not specially designated in the lists are deciduous. The 

 others are followed by special marks, such as B, broad-leaf evergreens; C, 

 cone-bearing evergreens; H, half evergreens; that is, hold their leaves until 

 midwinter or after; P, palms or palmlike.
