Sugar maple, Norway maple and silver maple all have extremely shallow roots, especially silver maples, which often have large, exposed roots well above the ground level. This makes it difficult to nearly impossible for grass or other plants to live underneath a silver maple tree.

This genus contains mostly species that are deciduous trees growing to 10 to 45m (30 to 145ft) in height, see Maple pictures on this page.ther species of the Acer genus are shrubs less than 10m (30ft) tall with a number of small trunks (and or branches) originating at ground level.
