Verticillium wilt (fungus) is a potential problem for maples; maple bladder gall.
Disease, pest, and problem resistance
This hybrid has the strong branch attachment of the red maple and fast growth rate of the silver maple.
Less susceptible to chlorosis symptoms (yellowing leaves) than red or silver maples.
Native geographic location and habitat
Of hybrid origin, a cross between two native trees, red maple (Acer rubrum) and silver maple (Acer saccharinum).
Bark color and texture
Bark is fairly smooth and silver-gray, becoming fissured with age.
Leaf or needle arrangement, size, shape, and texture
Simple leaves in pairs (opposite); 3 to 5 inches long.
