Acer听脳听freemanii,听Freeman maple听or听Freeman's maple, is a naturally occurring hybrid听听that is the result of a cross between听听(red maple) and听听(silver maple). Wild specimens are found in eastern North America where the parent species overlap. The species is named for Oliver M. Freeman of the听听who hybridized听A. rubrum听with听A. saccharinum听in 1933. The fall foliage is a striking orange-red. It has many commercially available cultivars and is frequently used as a听.
Cultivars
The cultivars are typically deliberately hybridized and听听in nurseries, not drawn from the wild specimens. Usually infertile (a desirable trait in cultivated maples), they have stronger branch attachments than silver maples and faster growth rates than red maples.

Description
Even high-powered morphometric analyses of leaf shape cannot easily distinguish听Acer 脳 freemanii听individuals from the parent species.听All that can be said is that听Acer 脳 freemanii听is generally intermediate between the parents.[]
