ACER rubrum 'October Brilliance'

Family

Aceraceae

Botanical Name

ACER rubrum 'October Brilliance'

Plant Common Name

Northern Red Maple, Red Maple

General Description

A little known cultivar one of the most widespread North American maples, 'October Brilliance' unfurls its leaves relatively late in spring, when damaging frost is less likely. Said to be of dense and compact habit, it has three-lobed or weakly five-lobed, mid-green leaves with paler undersides. The foliage turns orange or red in fall. Conspicuous red flowers appear in late winter and early spring. This male cultivar produces no seed. Winter interest is provided by stark gray bark that is smooth in youth and scaly on older trees.

This tough, cold-hardy deciduous tree is adapted to a wide range of soils and topographies, including wet sites. Red maple grows best in locations with full to part sun and makes a great shade tree or street tree for urban or rural settings.
