Liana (Climbing Vine) Parthenocissus tricuspidata [Boston Ivy] One of the strongest-climbing vines, give solid support for attachment of the adhesive discs on tendrils. Not a vine for trellises or fences. Very tolerant of urban soils. Not a good groundcover.
Shrub Philadelphus coronarius [Sweet Mockorange] Well adapted to different light (even shade) and soil conditions, especially to dry situations. Relatively trouble-free, and one of the most fragrant of the mockoranges. None of the mockoranges have much landscape interest after the season of bloom. Becomes leggy if not pruned. Pruning should be done after flowering (flower buds form on previous years wood), and to maintain fullness of form.
Tree Pinus parviflora [Japanese White Pine] The species exhibits good salt tolerance. Although subject to rusts, wood rots, nematodes, and sawflies, none are serious.
Tree Indiana Native Platanus occidentalis [American Sycamore] One of the largest of shade trees, making massive, majestic specimens. Tolerant of urban conditions, but generally found in riparian areas in the wild. The mottled, multi-colored, exfoliating bark is very beautiful and makes for excellent winter interest. Needs a large volume of soil space. Anthracnose leaf and twig blight occasionally disfigure this tree, and can damage it severely. Leaves, twigs, bark, and fruit contribute to a significant litter problem. Although this species can tolerate…
Shrub/Tree Platycladus orientalis [Oriental Arborvitae] Best in at least fairly moist soils, and with fairly high humidity. Habit tends toward becoming thinner (open) with age. Subject to "winter-burn" near the edge of its useful range. Certain forms provide very positive accent, but can be over-used. Bagworms can also be a problem.
Tree Indiana Native Prunus serotina [Black Cherry] Probably the best native-American species of cherry for landscape use, but still useful only in a few situations, especially for naturalizing. A valuable timber tree, especially for furniture. Subject to several minor pests, none usually serious in naturalized situations. Wood is slightly brittle. Eastern tent caterpillar problematic is some years.
Tree Pseudolarix amabilis [Golden Larch] No serious diseases. Should be protected from too much wind.
Shrub Pyracantha coccinea 'Lalandei' [Lalandei Scarlet Firethorn] A favorite for espalier training, because of the adaptable branching habit, showy fruits, and vigourous growth. Adapted to a variety of soils and environments but is susceptible to scab. 'Lalandei' is the most popular Scarlet Firethorn cultivar in northern areas, although it may winter burn.
Tree InvasiveThis plant is considered invasive Pyrus calleryana [Callery Pear] Overused, weak wooded, short-lived. Flowers are malodorous and often killed by late spring freezes. Some fireblight susceptiblity. Forms narrow crotch angles that can result in a larger tree literally splitting in two. Very small fruits are a litter problem when abundant. Considered invasive in many areas.
Tree InvasiveThis plant is considered invasive Pyrus calleryana 'Glen’s Form' [sold as Chanticleer®] [Chanticleer Callery Pear] Generally considered to be one of the best cultivars of P. calleryana. While still prone to limb breakage, it is stronger wooded than other variants. The Chanticleer Callery Pear is also known for its resistance to fireblight. Flowers are malodorous and often killed by late spring freezes. Very small fruits are a litter problem when abundant. Considered invasive in many areas.
