Maple Collec`on Cornell Planta`ons Plant List Last Updated 7/31/12 Common Name Scientific Name Acer ×conspicuum 'Silver Vein' FREEMAN MAPLE Acer ×freemanii 'Celzam' CELEBRATION FREEMAN MAPLE Acer ×freemanii 'DTR 120' AUTUMN FANTASY™ FREEMAN MAPLE Acer ×freemanii 'Jeffersred' AUTUMN BLAZE® FREEMAN MAPLE Acer ×freemanii 'Marmo' FREEMAN MAPLE 1 Notes Medium-‐sized, slender tree or multistemmed shrub to 10m tall. Trunks and branches very heavily striped with white on a blue-‐green bark. This hybrid was found in Hilliers' nurseries about 1960 and named about 1975. It was supposed to be a hybrid betweeen A. pensylvanicum and A. pectinatum ssp. laxiflorium; in fact, it is a seeding from the cross between A. davidii 'George Forrest' and A. pensylvanicum 'Erythrocladum'. It is a very valuable plant, worthy of a place in the garden. It has the most conspicuous bark of all snakebark maples. A compact, pyramidal tree reaching 45-‐50' in height and 20-‐25' in width. Noted for its strong crotch angles and inwardly cupped limbs that withstand snow loads and severe winds. Dense foliage is disease resistant, and assumes red and gold hues, regardless of weather conditions in October. Male clone. Tree with an upright oval habit, leave are 5 lobed and more closely resembling Silver rather than Red Maple. Attractive crimson fall color. Original tree from central Illinois. Rapid-‐growing tree, reaching 40' to 50' in height, with an oval-‐rounded head, and ascending branch structure with central leader. Foliage deep green, deeply lobed, developing excellent orange-‐red fall color, that persists later than that of many cultivars. May be more drought-‐tolerant than A. rubrum cultivars. A distinctly broad-‐columnar tree reaching 70' in height and 35-‐40' in width. Fall color is exceptional, the color starting to develop in mid-‐September in Lisle, Illinois, with red predominating, interspersed with green patches, the color lasting for 2 to 4 weeks. Common Name Scientific Name Acer ×freemanii 'Morgan' FREEMAN MAPLE Acer ×freemanii 'Scarsen' SCARLET SENTINEL™ FREEMAN MAPLE Acer ×freemanii 'Sienna' SIENNA GLEN™ FREEMAN MAPLE Acer ×freemanii 'UMNAF#1' FIREFALL™ FREEMAN MAPLE Acer ×zoeschense MAPLE 2 Notes A very fast-‐growing selection that reaches 45-‐ 50' in height and 40' in width, developing an open, oval-‐rounded habit; fall color a brilliant orange-‐red to red, colors well even in mild climates, reputed to have the brightest color of all red/freeman maples, and to be hardier than other freeman selections; female. Oval-‐rectangular tree with a strong upright growing habit, reaching 35'-‐40' in height. Foliage dark green, larger than the type, turing yellow, orange, and red in fall. Holds up well in summer heat. Pyramidal tree to 50' tall and 35' across. Green foliage turns rusty orange to burgandy in fall. This hardy hybrid maple was discovered in Minnesota. It features a strong central leader and develops a pyramidal form with minimal pruning. (AAN December 15, 2004 p.22) Wood is resistant to sunscald and frost cracking. Discovered on an abandoned farm site in Lake Elmo, MN. Firefall™ Freeman maple is a large shade tree that will provide outstanding fall color in northern regions. . Firefall™ has an upright-‐ oval form with good branch angles. The foliage is an attractive medium green through the summer. Fall color is bright orange to scarlet and develops fairly early, around late September to early October. This is a distinct advantage over some existing Freeman maple cultivars that color later and often don't develop much color in northern regions before freezing temperatures cause the foliage to drop. A hybrid of garden origin. A medium-‐sized tree reaching 15m in height, often wider than tall and densely branched, the branches slightly corky, yellow-‐brown, minutely pubescent, or in some grexes the branchlets chestnut-‐brown or turning grayish-‐brown. Leaves 5-‐7-‐lobed, 10-‐20cm across; flowers yellow-‐green, appearing after the leaves in terminal, erect corymbs. Fall color yellow to golden brown.

Richard would know the history more than me, but we were told it was a broom and it was a red maple. Tree with an oval crown and upright spreading branches, and a strong central leader, its form more regular than that of the typical silver maple. Leaf form typical of the species, golden yellow in fall; seedless selection. More upright horizontal branching habit than some of the other cutleaf varieties. Yellow fall color. Plants to 60' tall. Tree to 40m; crown rounded; bark furrowed, grey. Branches glabrous, brown-‐gray. Leaves to 14cm wide, cordate at base, dull green above, pale grey-‐green beneath, Fruit glabrous, wings held near parallel, to 4cm. A pyramidal, upright tree growing to 75' tall and 30' across, with compact, ascending branching structure. Dense, dark green foliage retains its color late into the fall season. Fall color is a golden-‐orange two weeks later than other sugar maples. Habit upright and densely pyramidal, shaped like an arrowhead with dense branching and a strong central leader. Plants reach 40' in height and 60' in width. Summer foliage good quality; fall color orange to red. Selected at Schichtel's Nursery, Springville, NY. (1984 Schichtel's catalog). Tree with a refined narrowly oval habit composed of symmetrically and evenly spaced upright branches that reaches 45' in height and 20' in width; an unusually vigorous grower that has shown remarkable heat tolerance and resistance to leaf tatter; fall color is yellow and orange. Tree that has an upright oval growth habit with ascending branches and is somewhat columnar. Early fall color, yellow to orange-‐ red.

Summer foliage is thick, leathery, glossy green, fall colors are yellow, orange and red. Foliage is resitant to leaf tatter. Selected from a seedling population in Oregon. Plants reach 25' in height and 10' in width in 30 years when grown in an urban environment. Growth rate is slow, producing a tree with dense branches, short internodes, and a symmetrical, narrow, tightly columnar shape. Dark green summer foliage turns yellowish-‐orange to red in autumn. Plants 50' to 75' tall, with broad oval shape. Fine polished green leaves turn brilliant red in the fall. A vigorous, rapid grower which calipers up especially rapidly and exhibits good heat tolerance; A vigorous grower with a broad, oval canopy; appears to be the fastest growing cultivar, and exhibits good heat tolerance and resistance to leaf hopper (DS 318). Caddo maples are a little-‐known variant of sugar maple found in the canyons of Caddo and Canadian Counties in Oklahoma. They thrive in soils having a pH of 7.5 and tolerate drought and heat without a hint of leaf scorch or tatter; smaller than the typical sugar maple; fall color is reddish and can be outstanding although it develops very late in the season.

Fast growing, straight selection with good branching. Orange and scarlet in fall. Resistant to frost cracking. Selected from Caddo Mountain sugar maple seedlings, this tree has the brightest red fall color we have seen in a cultivar adapted to Southern heat. It features dark green summer foliage, better mildew resistance than other Caddo selections, strong growth, and brilliant red, early fall color. Strong upright growth and reliable, early fall color make this a standout in the nursery and on the streets. Vigorous, with a good central leader, it is faster growing with a more upright shape than typical of sugar maples. Tree with a broad, oval growth habit with a dense crown of broadly ascending branches. Leaves turn red in early fall. Narrowly columnar tree to 50' tall with a 14' spread. The key idendifying characteristics of this cultivar are: a lack of a single central trunk above 6' from the ground; major and minor branches are vertical; short stubby lateral branchlets on secondary branches. This cultivar and 'Temple's Upright' were long confused in the literature, but are easily distinguished. Neither are currently easy to find in the trade. Dark green leathery foliage with good scorch resistance, supposedly turns scarlet in the fall but reports from the Midwest indicate that it turns yellow, and from the Pacific Northwest it turns yellowish-‐red. Upright oval crown; performs better than the species in dry, restricted growing areas; plants 7.2' tall and 5' wide after 4 years. Quite heat tolerant.
