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.
Tree InvasiveThis plant is considered invasive Phellodendron amurense [Amur Corktree] A striking tree for its interesting bark and massive framework. Widely adaptable to soil, trouble-free, and drought and pollution resistance. Easily transplanted. May be less hardy when young and rapidly growing. Fruits smell like turpentine when crushed (or stepped on). This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended plantings to invade and displace native hardwood forests. Note: only female plants have the potential to become invasive. Phellodendron amurense…
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.
Shrub Physocarpus opulifolius 'SMNPOTW' [sold as Tiny Wine®] [Tiny Wine Ninebark] Tiny Wine Ninebark is noted for its features as it is interesting season round. The exfoliating bark on mature wood reveals red-brown inner bark, this is how the common name Ninebark was chosen as the color is ever changing.
Tree Picea abies [Norway Spruce] Slight mite susceptibility in hot, dry sites. Some susceptibility to borers. May become thin, open, and have a less attractive habit at maturity.
Tree Picea glauca [White Spruce] Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Often found at the arctic tree line. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites. Except for its use in the far North, other evergreens have better overall aesthetics for Midwestern and Eastern states.
Shrub/Tree Picea glauca var. conica [Dwarf Alberta Spruce] This commonly available dwarf variety has a very dense, conical habit. Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites. Except for its use in the far North, other evergreens have better overall aesthetics for Midwestern and Eastern states.
Tree Picea glauca var. densata [Black Hills Spruce] Widely considered a superior form, this variety is denser and more compact with brighter foliage, when compared to the straight species . Best in full sun, but tolerates some shade. Withstands heat, cold, drought, wind, and crowding. Slight susceptibility to trunk and root rots, bagworms, sawflies, and mites.
Tree Picea orientalis [Oriental Spruce] Generally considered a better choice for the landscape than P. abies (Norway Spruce) or P. glauca (White Spruce). Best in cooler climates; does not always tolerate southern heat and humidity well. In order to prevent desiccation and needle browning, protection from harsh winter winds is advisable for plants grown in colder climates.
Tree Picea pungens [Colorado Spruce] One of the most striking of the conifers in color and habit, especially f. glauca. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color (especially prominent in f. glauca) does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
