Tree Indiana Native Acer saccharum ssp. nigrum [Black Maple] The Black Maple is a close relative of the Sugar Maple. Typically, Black Maples tolerate and grow in wetter soils than the Sugar Maple, but they are equally shade tolerant. Black Maples do not tolerate salts and are therefore poor street trees. This species prefers deep, uncompacted soils.
Tree Acer tataricum ssp. ginnala 'Flame' [Flame Amur Maple] Extremely hardy small tree with interesting foliage (elongated center lobe) and colorful fruits. Widely adapted and trouble-free. Prefers sun but tolerates some shade. Good for growth in large planters. Among first trees to leaf out. Withstands heavy pruning. Can be damaged by ice stroms. Verticillium susceptible, but rare.
Tree Acer triflorum [Three-Flower Maple] Acer triflorum tends to be an understory tree in its natural habitat. Its beautiful exfoliating bark reveals a rusty brown coloration, providing attractive winter interest. Its shallow root system cannot handle drought well, unless properly mulched. This maple can handle full shade but is best in part shade to full sun.
Tree Acer × freemanii 'Armstrong' [Armstrong Red Maple] The Armstrong Red Maple is a cross between Acer rubrum and Acer saccharinum and is known for its columnar habit and brilliant red to red-orange fall coloration. This species has the durability of the Silver Maple and can tolerate urban conditions. The root system is less aggressive, though, so it can be planted as a street tree.
Tree Acer × freemanii 'Jeffersred' [sold as Autumn Blaze®] [Autumn Blaze Maple] This cultivar is among the best for fall foliage of both Red and hybrid Red Maples. It is an extremely fast grower and appears to be more drought tolerant than most Acer rubrum cultivars. 'Jeffersred', is often sold under the tradmark name, Autumn Blaze.
Tree Acer × freemanii 'Marmo' [Marmo Freeman Maple] The Marmo Maple has similar characteristics to its Silver Maple parent, more so than to its Red Maple parent. This cultivar produces staminate flowers, and therefore is seedless. 'Marmo' fall color ranges from reds to greens. Once established, it becomes tolerant to most pests and disease.
Tree Acer × freemanii 'Scarsen' [sold as Scarlet Sentinel®] [Scarlet Sentinel Freeman Maple] This cultivar is a cross between the Red Maple and the Silver Maple, though it's leaves and bark more closely resemble the Silver Maple. It is one of the most adapted maples for southern regions of the country. 'Scarsen' is known for its colorful yellow-orange to orange-red fall foliage and columnar growth form.
Shrub Indiana Native Aesculus parviflora [Bottlebrush Buckeye] Can be kept at a smaller size for a time with careful pruning, but it will in time occupy much space. Tolerates some shade, and can even be attractive under large shade trees. Suckers quite freely.
Shrub Alnus serrulata [Hazel Alder] Closely related to Alnus rugosa, differing chiefly in its leaves, which are usually broadest above the middle and have the margins set with fine, nearly regular teeth. Multi-stemmed habit and tends to sucker.
Tree Indiana Native Amelanchier arborea [Downy Serviceberry] Would grow well on a streambank. Susceptible to rust, leaf blight, powdery mildew, fruit rot, leaf minor, borers, and scale. Rarely requires pruning.
