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.
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…
Tree Amelanchier laevis 'Cumulus' [Cumulus Allegheny Serviceberry] Amelanchier laevis 'Cumulus' is a single-stemmed, strongly upright small tree, excellent as a small street tree and for very early, but short-lived, blooms. This tree is sometimes grafted, so rootstock suckers can be a problem. Fruits are edible and a prime source of food for birds. Subject to the troubles of Rosaceous plants in general, including fire-blight and mites, which can be controlled, usually quite easily.
Tree Carpinus betulus [European Hornbeam] Carpinus betulus is relatively trouble-free and tolerates a wide range of soil conditions and some shade. This plant is also very tolerant of heavy pruning, making it useful as a hedge.
Tree Carpinus betulus 'Columnaris' [Columnar European Hornbeam] Carpinus betulus is relatively trouble-free and tolerates a wide range of soil conditions and some shade. This plant is also very tolerant of heavy pruning, making it useful as a hedge. The cultivar 'Columnaris' is a narrow, columnar cultivar that is slow-growing with densely set branches and leaves.
Tree Carpinus betulus 'Fastigiata' [Fastigiate European Hornbeam] Carpinus betulus is relatively trouble-free and tolerates a wide range of soil conditions and some shade. This plant is also very tolerant of heavy pruning, making it useful as a hedge. The cultivar 'Fastigiata' is a narrow, columnar cultivar with densely set, broom-like branches. Over time this cultivar tends to broaden and open up into a more oval-vase form.
Tree Carpinus betulus 'Frans Fontaine' [Columnar European Hornbeam] Carpinus betulus is relatively trouble-free and tolerates a wide range of soil conditions and some shade. This plant is also very tolerant of heavy pruning, making it useful as a hedge. The cultivar 'Frans Fontaine' is a tight, narrow, columnar cultivar with densely set branches and leaves. Over time this cultivar retains its fastigiate form better than the similar cultivar 'Fastigiata'.
Tree Carpinus betulus 'JFS-KW1CB' [sold as Emerald Avenue®] [Emerald Avenue® Hornbeam] This European Hornbeam cultivar has dark green pleated leaves with double serrated margins in the summer. In the fall the leaves mature to a golden yellow on stout branches. This tree also has a tight broad pyramidal to ovate shape and great heat tolerance, making it a desirable street tree.
Tree Indiana Native Carpinus caroliniana [American Hornbeam] A clean, trouble-free small tree, useful in intensive situations such as patios and malls, and equally interesting in naturalized plantings. Useful as a large hedge if coppiced when young. Performs well in heavy shade and tolerates periodic flooding. Difficult to transplant. Move balled-and-burlapped for best results. Sometimes called Blue Beech and Ironwood (although these are best not used).
Tree Castanea mollissima [Chinese Chestnut] Overall tough and durable, but can be susceptible to blight, twig canker, and orient chestnut wasp. Also susceptible to weevils, which damages the roots. Prefers well-drained, loamy soils, full sun, and hot, arid conditions.
