Freeman maples are hybrids of red maple and silver maple, both of which are native to Minnesota and to the eastern United States. Cultivars of Freeman maples combine the best features of each parental species: stronger wood and branch attachments, good plant form, and red or orange autumn color from red maple and the rapid growth rate, improved drought tolerance, tolerance to higher soil pH, and general adaptability to difficult climatic and soil conditions from silver maple. Freeman maples can be used in urban landscapes as specimen or accent plants and as shade or boulevard trees. Plant Freeman maples in full sun for best fall color. Maples are thin-barked species and are susceptible to frost cracks and sunscald; young trees should be protected with tree guards during winter. Root systems are shallow and can appear above ground with age, making mowing difficult.
Clusters of flowers appear on Freeman maples in spring followed by 5-lobed, 3-5" leaves. Leaf shape is intermediate between silver and red maple and varies from cultivar to cultivar. The fruit is a winged nutlet called a samara that is produced in fused pairs. Fruit ripens quickly and falls in April and May. Some cultivars are seedless. Freeman maples are of particular interest in two seasons: summer and fall. Several cultivars have large, dense canopies that offer much shade during summer months. Freeman maple's main season of interest is autumn because cultivars have been selected for their outstanding orange, red, and yellow fall color.
