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 grandidentatum [Bigtooth Maple] A densely branched tree with shiny green lobulate leaves on top and silvery beneath. It has a bright fall color of red, yellow, and orange as well as yellow corymbose flowers in spring. The samaras resemble moth wings.
Tree Indiana Native Acer negundo [Boxelder] Invasive. Very rough in its appearance due to pinnately compound, coarsely serrate leaves paired with a multi-stemmed, irregular habit. Leaves of young specimens may commonly be mistaken for poison ivy. This tree has limited ornamental value in the landscape and is short lived but also extremely tolerant of site conditions. Wherever this species is grown, expect to encounter boxelder bugs (Leptocoris trivittatus). This common pest feeds on the sap of boxelders and maples and is…
Tree InvasiveThis plant is considered invasive Acer platanoides [Norway Maple] One of the densest shade trees, widely adaptable to soils and environments, including dry and polluted city conditions. Transplants easily. Extremely dense canopy and shallow root system make it impossible to maintain good turf beneath. Can be a weed problem, especially in cooler parts of the northeast US. Slight susceptibility to verticillium wilt, anthracnose, and leaf scorch. Can be damaged by 2,4-D drift. Does not perform well in southern US (warm nights severely retard growth).…
Tree InvasiveThis plant is considered invasive Acer platanoides 'Columnare' [Columnar Norway Maple] This cultivar is easy to transplant and is tolerant of different soils. The Columnar Norway Maple is more adaptable to drought than other Maples. Pollution tolerant. 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 reproduction of native…
Tree InvasiveThis plant is considered invasive Acer platanoides 'Crimson King' [Crimson King Norway Maple] Crimson King is a common cultivar used in the industry for its rich maroon foliage throughout the growing season. One of the densest shade trees, widely adaptable to soils and environments, including dry and polluted city conditions. Transplants easily. Extremely dense canopy and shallow root system make it impossible to maintain good turf beneath. Slight susceptibility to verticillium wilt, anthracnose, and leaf scorch. When Norway maple escapes cultivation and invades natural areas it reduces species…
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 rubrum [Red Maple] Tolerant of wet, poorly drained soils and as well as dry conditions. Weak wooded. Intermediate in quality between A. saccharum and A. saccharinum, somewhat prone to breakage in storms, but generally satisfactory. Does not tolerate heavy pollution.
