Identification

• The aspen tree's trunk is thin and light gray or green-gray in color. Thin branches extend from it, ending in flat, thin, round leaves.
  
  

Size

• In highland regions, the average height of an aspen tree is 30 feet, though some members of the species can grow twice that height.
  
  

Soil Preference

• Aspen trees grow in moist, light soils. They grow best in soil that is slightly acidic.
  
  

Geography

• Aspen trees have a wide habitat range. They grow in China and Japan to the north, throughout Russia and Europe, in Northern Africa, and in North America.
  
  

Considerations

• Aspen trees are difficult for gardeners to keep because they attract insects, are prone to diseases such as oyster shell scales and leaf spot disease, and are very particular about soil content.
