Amur Corktree
Phellodendron amurense

Height: 30-45'
Habit: : broad rounded, spreading

Landscape Value:

This "unusually pest-free" tree is particularly valuable in park and urban situations. It has wide-spreading, massive branches and picturesque, open shape. It transplants easily and develops a shallow, spreading root system. Able to withstand many cultural extremes such as acid to alkaline soils, different soil types, and air pollution, it should be used more often.

Seasonal Characteristics:

• Summer: Nice dark green, glossy foliage in the canopy provides pleasant shade.
  
  
• Fall: Female trees have fruits (drupes) that turn from green to black as they ripen. The fall color is only of passing interest because it is short-lived and yellow to yellow-bronze.
  
  
• Winter: The gray-brown bark is ridged and furrowed, looking corky. The bark pattern develops as the tree reaches maturity. Stout stems give the tree a coarse texture.

Points of Interest:

Its thick, corky bark has been regarded at as a source of cork but has proven to have little economic value. Easy to propagate, the seeds germinate without pretreatment.

Native Range:

Northern China, Manchuria, and Japan.
