Tree Acer buergerianum [Trident Maple] Needs training to develop single central leader (if that is desired). Popular street tree in Japan. Cold hardiness varies in seed produced stock. In some cases, fruit set is so high as to deplete foliage. Flaking bicolor bark in gray-brown and orange.
Tree Acer campestre [Hedge Maple] Transplants easily. Pruning may be needed to limb up branches to create a shade or patio tree. Tolerates severe pruning and soil compaction. Can be pruned to become a giant hedge.
Tree Acer griseum [Paperbark Maple] Slow growth (6-12" per year) is compensated for by longevity and freedom from maintenance. The cinnamon-brown, curly bark is outstanding. Habit is open enough to display bark interest year-round.
Tree Acer miyabei [Miyabe Maple] Attractive bark is grayish with long, vertical scales and fissures in maturity. Some difficulty in both vegetative and seed propagation.
Tree Acer miyabei 'Morton' [sold as State Street™] [State Street Miyabe Maple] This selection has handsome corky bark with an oval form and attractive ascending branches. Acer miyabei 'Morton' is sometimes known as an alternative to Acer campestre, as it is more vigorous and cold hardy.
Tree Acer palmatum [Japanese Maple] A refined but striking specimen in its several forms, differing in color, texture, and habit, but all graceful. Newly expanded foliage may be damaged by sun and wind. Plant where it will receive some protection from the elements, especially winter elements. Can leaf out early and be killed back by a late freeze. Prefers some shade and good moisture.
Tree InvasiveThis plant is considered invasive Acer platanoides 'Emerald Queen' [Emerald Queen Norway Maple] This cultivar has ascending branches and an oval habit. Best selection of Norway Maples for urban sites. Fast growth rate and shallow root system. Brilliant yellow in the fall. When Norway maple escapes cultivation and invades natural areas it reduces species richness and native tree regeneration by out-competing other trees and understory species for resources, creating dense shade canopies, and spreading rapidly through high seed production. It also releases toxins that reduce the growth and…
Tree Acer pseudoplatanus [Sycamore Maple] Tolerates salt spray. Produces a lot of dead wood that needs removal. Anthracnose and canker disease can be serious.
Tree Indiana Native Acer saccharum [Sugar Maple] Widely adapted to climate, but best in at least reasonably fertile soil. One of the best shade tree species over a wide area, but for best results select plants known for adaptability to the local region. Quite shade tolerant. Low maintenance in a good site. 50 gal. sap or more needed to make 1 gal. syrup. Not so drought-tolerant as silver maple, but reasonably so. Does poorly in compacted soils, and doesn't like salt spray.…
Tree InvasiveThis plant is considered invasive Ailanthus altissima [Tree of Heaven] Unusual form and texture not unlike a large sumac. Highly adaptable. Tolerates salt spray. Dioecious. Coarse and inclined to drop twigs. Male flowers are malodorous; female plants make many weed seedlings. Ailanthus altissima forms dense, clonal thickets which displace native species and can rapidly invade fields, meadows, and harvested forests. This invasive tree species is extremely tolerant of poor soil conditions and can even grow in cement cracks. Ailanthus altissima is not shade tolerant, but…
