Autumn Flame red maple is a patented plant that was selected and introduced to commerce in the mid 1960s. It is one of the earliest red maples to exhibit fall color and is very rounded in mature form.

This tree is not as hardy as many of the newer selections; it was killed outright in some northern states during the difficult winters of the late 1970s. It has been a steady reliable performer in KY and is still produced regularly by nurseries here.
