Acer x freemanii JeffersredAutumn Blaze
maple
  • SIZE Medium tree
  • HABIT Oval - rounded, dense crown
  • FOL Rich green in summer long-lasting
    orange-red in fall deeply lobed leaf similar to
    Acer saccharinum
  • FL. FR. Red in Spring a mix of male and
    female and hermaphroditic flowers fruit a
    reddish samara in early summer

2
CULTURE Tolerates most soils tolerates air
pollution but not a great urban tree does not
like salt! PESTS none serious USE Specimen tree
for lawn, street, or park MISC. Selected in the
1960s by nurseryman Glenn Jeffers in Fostoria,
OH. Introduced in 1980. From seedlings
collected from a cross of A. rubrum x A.
saccharinum. A. x freemanii was first developed
in 1933 at the U.S. National Arboretum by Oliver
Freeman

ridges and furrows. Twigs tend to be covered
with a glucose bloom.
6
FLOWERS and FRUIT Dioecious, yellow-green in
Spring male flowers in corymbs female in racemes

10
  • CULTURE Performs well in poor, wet or dry
    soils pH adaptable. Will survive where other
    trees will not!

11
PESTS Anthracnose, leaf spot, and powdery
mildew boxelder bugs USE Weedy, trash
tree use only where all other trees
fail! MISC. Flamingo pink shoots with
green leaves and white margins. Plant a male
selection to eliminate messy female samaras

    deficiency

32
USE Specimen tree for lawn, street, or
