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 'Celzam' [sold as Celebration®] [Celebration Freeman Maple] 'Celzam' has a classic upright form with uniform growth, making for a great specimen tree in the landscape. This plant, like most Freeman hybrids, is generally seedless and is also known for its fall color. In early October, 'Celzam' becomes a brilliant red and then slowly changes to gold by late October.
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 Aesculus × carnea 'Briotii' [Ruby Red Horsechestnut] Has decent tolerance to drought and urban environments. Buds are not as sticky as its parent plant, Aesculus hippocastanum. Flower panicles are larger than both parent species with a rich red coloration, making it a popular tree choice in England.
Tree Indiana Native Aesculus flava [Yellow Buckeye] The Yellow Buckeye is a large, majestic native tree that is widely adapted to soils and environments; however, very dry conditions must be avoided. Drought causes early leaf drop and leaf blotch, and leaf scorch can disfigure foliage in dry soil. That being said, this species is less prone to foliar problems than the related Aesculus glabra (Ohio Buckeye) is. Difficult to transplant once established due to long taproot. Large, abundant fruits in autumn can…
Tree Indiana Native Aesculus glabra [Ohio Buckeye] Widely adapted to soils and environments; however, very dry conditions must be avoided. Drought causes early leaf drop. Leaf blotch and leaf scorch often disfigure foliage, especially in dry soil. Spiny fruits in autumn can be troublesome underfoot, and eliminates species type as a good street tree. Fruits are toxic, containing 3-5% saponins.
Tree Aesculus hippocastanum [Common Horsechestnut] Widely adapted to soils and environments; however, very dry conditions must be avoided. Leaf blotch often disfigures foliage. Spiny fruits in autumn can be troublesome underfoot, and eliminates species type as a good street tree. Fruits are toxic containing 3-5% saponins.
Tree Aesculus hippocastanum 'Baumannii' [Baumann Common Horsechestnut] 'Baumannii' is known for its large panicles of double flowers. The flowers are sterile, so none of the large, littering, poisonous fruit of the species type are produced, increasing this tree's usability. Widely adapted to soils and environments; however, very dry conditions must be avoided. Leaf blotch often disfigures foliage.
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.
