Sienna Glen Maple

Acer x freemanii ‘Sienna’

The Sienna Glen Maple tree is a naturally occurring hybrid found on an abandoned farmstead in Lake Elmo, Minnesota. Its distinct, upright, pyramidal growth habit, which is readily apparent as a young tree, grows and becomes a broad pyramid when mature. The Sienna Glen exhibits vigorous growth yet withstands strong winds. The branches are borne more closely together along the trunk (than those of Autumn Blaze) and are finer and more delicate, yet the wood is harder and shorter and exhibit less drooping. The smaller, fine textured green leaves are dark green with a silvery underside and turn a variable mix of yellow and orange with a pinkish tinge at the highest part of the crown. As the fall color finishes, it turns a burnt orange. This beauty tolerates higher soil pH unlike Autumn Blaze, not exhibiting any chlorosis. Hardiness zone 4 (testing done in zone 3). Mature growth is around 60′ tall x 40′ wide.

It has a high canopy with a typical clearance of 6 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a medium rate, and under ideal conditions can be expected to live for 70 years or more. This tree should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.

Firefall™ Maple Acer x freemanii 'Firefall' Firefall™ has an upright-oval form with good branch angles. This selection is male and therefore does not produce nuisance seeds. The foliage is an attractive medium green throughout the summer. Fall color is bright orange to scarlet and develops fairly early. This is a distinct advantage over some  existing Freeman maple cultivars that color later and often do not develop much color in northern regions before freezing temperatures cause the foliage tomdrop.

Prefers moist, acidic soils with good drainage. Established trees have some tolerance for drought conditions. Noteworthy Characteristics Acer x freemanii, commonly called Freeman maple, is a hybrid of red maple (A. rubrum) and silver maple (A. saccharinum). The Freeman maple cultivars commonly sold in commerce today reportedly combine some of the best features of both parents, namely, solid structure, attractive form and showy fall color (from red maple) and adaptability and rapid growth (from silver maple). Oliver M. Freeman of the National Arboretum made the first controlled crosses between red maple and silver maple in 1933. Edward Murray named this hybrid cross in 1969 in honor of Oliver M. Freeman. Notwithstanding the foregoing, crosses between red and silver maples occur not only by controlled propagation but also naturally in the wild. It is sometimes difficult to identify a Freeman hybrid because of the complexity of crosses and backcrosses that may occur. Cultivars are sometimes listed for sale by nurseries under Acer rubrum instead of Acer x freemanii. Genus name is the Latin name for a maple tree. Specific epithet and common name honors Oliver Freeman who first grew A. x freemani at the U. S. National Arboretum in 1933. ‘Jeffersred’, sold under the trade name of AUTUMN BLAZE, is an older cultivar that was discovered by nurseryman Glenn Jeffers in the late 1960s. This is an upright, fast-growing, deciduous tree that will typically grow 40-55’ tall with ascending branching and a dense, broad-oval crown. Each medium green leaf is deeply cut with five pointed lobes. As the trade name suggests, the foliage turns into an autumn blaze of orange-red to scarlet-red fall color. Flowers and fruit for this hybrid are very sparse. U.S. Plant Patent PP04,864 issued July 6, 1982. Problems No serious insect or disease problems. Young plants susceptible to leafhoppers and scale. Borers.
