Native geographic location and habitat:

This is of  hybrid origin. It is 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, that becomes fissured with age.

Leaf or needle arrangement, size, shape, and texture:

Simple leaves in pairs (opposite) grow 3 to 5 inches long. The 5-lobed leaves are deeply lobed, with toothed sinuses that often resemble those of silver maple. They are medium green with a silvery underside. Fall color is an interesting mottled blend of red and green to burgundy, and yellow.

Flower arrangement, shape, and size:

Flowers are inconspicuous. ‘Marmo’ has only male flowers.

Fruit, cone, nut, and seed descriptions:

This tree produces no fruit.

Plant care:

Avoid pruning maples in spring as they are ‘bleeders’ and will lose large amounts of sap.

List of pests, diseases, and tolerances:

Verticillium wilt (fungus) and maple bladder gall are potential problems for maples. This hybrid has the strong branch attachment of the red maple and fast growth rate of the silver maple. It is less susceptible to chlorosis symptoms (yellowing leaves) than red or silver maples.
