Tree Indiana Native Nyssa sylvatica [Black Gum] Especially useful in wet soils. One of the most beautiful of trees, with habit comparable to Quercus palustris, but usually more irregular, and with a greater number of more slender main limbs. Silvery-gray, picturesque branching; strong horizontal accent. Difficult to transplant due to taproot; use container-grown plants when possible, or at least plants dug with a soil ball. Shelter from wind. In the North, select native northern stock as the species has a wide geographic…
Tree Indiana Native Ostrya virginiana [American Hophornbeam] A good, trouble-free small shade tree worthy of greater use. Very graceful with many drooping branches that create a rounded habit. Best on drier slopes, and is usually found in native ecosystems. Slow growing, and difficult to transplant. Does not tolerate periodic flooding (as does Carpinus caroliniana) or salt.
Tree Parrotia persica [Persian Parrotia] One of the best trees for foliage and bark effect. Very adaptable, tolerating drought, various soils, heat, cold, etc. Prefers full sun but tolerates light shade. Sites with strong winter winds will surely cause tip dieback in Northern Indiana.
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.
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 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 '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.
