Parkinsonia ×

[Hybrid Palo Verde]

Semi-evergreen leaves, and smooth line green trunks and branches year round. Palo Verde means "green stick" in Spanish, and the green bark carries on photosynthesis. Survives in the desert on natural rainfall once established. Few problems. Needs some minor clean up maintenance of flowers and leaves. Prune when young to develop multi-stems and show off the beautiful bark. 'Desert Museum' is a V-shaped thornless hybrid having genetic characteristics indicating complex hybridization between three species, Parkinsonia…

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.

Parrotia persica 'JLColumnar'

[Persian Spire™ Parrotia]

Parrotia persica 'Vanessa'

[Vanessa Persian Parrotia]

Vanessa is a cultivar that has a distinctly upright or columnar habit. 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.

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…

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.

Picea abies 'Cupressina'

[Columnar Norway Spruce]

Picea abies f. pendula

[Weeping Norway Spruce]

As its common name suggests, the Weeping Norway Spruce has a drooping habit and pendulous branches. This plant's irregular form varies depending on how it is trained, and it may even spread along the ground if left unsupported. Slight mite susceptibility in hot, dry sites. Some susceptibility to borers.

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.

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.
