We get many requests for red maple trees. It usually takes us a few minutes to narrow down exactly what kind of red maple we’re being asked for, since the term “Red Maple” could apply to several thousand distinctly different cultivars of trees. “Red maples” fall into four basic groups: true red maples, Norway maples with red foliage, upright Japanese maples, and weeping cut-leaf Japanese maples.


True red maples (Acer rubrum) are magnificent shade trees with green foliage that generally grow 50 feet tall and wide, although some get much larger. The species gets its name from its flower color, though most red maples have red seeds and red fall foliage as well. There are hundreds of cultivars, varying quite a bit in shape, growth habit, leaf color, hardiness and other traits. Our favorite is “October Glory”, because it gets spectacular red fall color and keeps its leaves for many weeks after they turn red.


There are other maples with red fall foliage, like the popular “Autumn Blaze”, which are not red maples at all. “Autumn Blaze” is actually a hybrid strain called Acer freemanii, a cross between red and silver maple.


Several cultivars of Norway maples (Acer platanoides) have purple or bronze foliage all season. “Crimson King” is the most popular, however “Royal Red” and “Faasen’s Black” are virtually identical. All have extremely dense, symmetrical crowns, grow very slowly, and are more compact than other maple shade trees. The dense shade and surface roots under Norway Maples make it difficult to grow lawns or other plants underneath.


Upright Japanese maples (Acer palmatum) make excellent ornamental trees (not shade trees) and many have red or purple foliage. “Bloodgood” and “Emperor” are two popular varieties, with the deepest red foliage and mature size of 15 to 20 feet tall and wide. Japanese maples do best with some protection from sun and wind. They make excellent accent plants, lending an artistic and aristocratic touch to the landscape.


Dwarf weeping Japanese maples (Acer palmatum dissectum) are extremely popular for foundation plantings and accents. Many have red foliage, including the popular “Crimson Queen”, “Tamukeyama” and “Inaba Shidare”. They tend to stay small (6 to 8 feet tall and wide) but can get much larger. The biggest one we’ve ever seen is at the Winterthur Museum gardens in Wilmington, Delaware and is over 50 years old. This magnificent specimen is 12 feet tall and at least 20 feet wide!


The confusion about red maples illustrates why nurserymen prefer to use botanical names when dealing with plants. Professional nurseries generally list plants using the “Latin binomial system”. Only by calling plants by their proper botanical names can we really be sure we’re getting the exact plant with the specific qualities we’re looking for. Think of the botanical name as a pedigree. The use of common names in plant advertising invites misunderstandings and can be an indication of poor quality plants.
