General Description

The Globose sugar maple has a rounded, well-branched canopy and thick, somewhat glossy green leaves that become a warm yellow with orange hints in autumn. This round-canopied, small, hardy deciduous tree is native to eastern North America and has large, broad, five-lobed leaves which become golden yellow in fall. In early spring, the branches are filled with tiny, pendent, light yellow-green flowers before the leaves emerge. Blossoms are visited by bees and result in the development of samaras: two winged seeds that are joined at the head and resemble helicopters as they drop and spiral downward to the ground.

Globose sugar maple develops the best crown growth in full to partial sun and tolerates a wide range of soil types. It isn't as adapted to stressful urban conditions as other maples but 'Globosum' is better suited to smaller gardens and yards, but do not plant near or under powerlines. It is slow growing and takes several decades to reach its fullest size. Its glossy lobed leaves are also thicker and less apt to tatter and are nicely summer heat tolerant.
