Bark peels in tight vertical curls. September brings a muted blend of yellow and claret-red foliage, capturing the essence of autumn. During winter, tufts of snow lodge on the peels of grey and honey-colored bark, lending contrast. Often listed as hardy to Zone 5, growers report it hardy to -40°F - a full zone rating hardier than Acer griseum.

Excellent trade name recognition because it is clearly a superior clone across a wide variety of Midwest and Eastern US climates. Grows to 20-25 ft. and develops reliable red-orange autumn color. The showy multi-colored fruits are relished by birds, and it never becomes obtrusive in the landscape.

Selected by Earl Cully almost 20 years ago for its outstanding peeling bark, extreme hardiness, resistance to borers, and ability to grow in waterlogged or dry soils. Whether you clump them in a container or grow them as singles, this is among the easiest of plants to finish: even our smallest liners can grow to 5-6 ft. in a single season. Named Urban Tree of The Year for 2002 by the Society of Municipal Arborists.

This is the most prized of white barked birch. It grows in classic conical form; it doesn't often look natural in a clump though it is often used that way. It is a easy to use adaptable tree.

Pest-free and widely adapted to conditions from the stream-side to the neighborhood mall. It's surprising the trade has not more widely embraced this American native. Fall color is an appealing mix of soft red, yellow and orange. Squirrels risk falling from the slenderest of branches to eat every possible fat, fertile seed in October.

Shiny dark green leaves and abundant, white, pleasantly fragrant flowers showcase this classy American native. Much hardier than C. retusus, it performs best in full sun and is remarkably versatile - from moist lowlands to dry hillsides. Among the finest of ALL landscape plants, not just natives.

Still uncommon in cultivation, this is an exceptional ornamental tree. Like Wisteria, it is most noted for its drooping clusters of fragrant white flowers, touched with yellow in the center. Introduced into cultivation by André Michaux in 1796, its roots were chipped and boiled to yield a yellow dye for homespun fabrics before synthetic dyes became available. Adapted across a wide range of soil pH, it prefers a reasonably moist, yet well-drained soil with full sun and space to grow.

Shrubby tree with a prominently horizontal, tiered branch pattern, suggesting its common name. Flat clusters of fragrant May flowers add to its layered ornamental appearance. Blue-black fruits ripen in late summer, followed by bronze autumn foliage.

From Shawn Mehlenbacher's work here at OSU comes a prized, blight-resistant, contorted, red-leaf hazelnut. With moderately contorted growth, it has an arching grace. Its purple color is intense in spring and early summer, and still dark later in the year. These are expensive but worth it; they will attract a lot of attention at garden centers.

Uncommon in American gardens, this medium to large tree ought to be used more for its pest-free character, corky bark, and symmetrical cone-shaped outline. Stays remarkably green through the toughest drought. Often used as rootstock for C. avellana 'Contorta' because it has less potential to produce suckers below the graft union as compared to C. avellana.

Stunning autumn color. Its flaming fall foliage rivals that of Sugar Maple. Thrives in rocky, dry areas where other trees languish. Larger leaves than C. coggygria and much taller in stature at maturity.

Among the most popular of the fruitless male selections. Not as strongly upright as the variety 'Fastigiata', Liners require staking early. With age it attains a handsome form and consistent brilliant gold color in autumn. This clone and 'Saratoga' come from the Saratoga Horticultural Foundation.

Very hardy - the rootstock of choice for a rich selection of new hybrids. These liners have an extensive root system - a bonus for field planting or potting up.

This species is prized for its small stature and remarkably beautiful flowers. The fragrant, nodding white blooms are accented by red stamens. Since this is a small tree, close inspection of the flowers is easy - a true delight! Although most references list it as zones 6-8, it has proved hardy at the Minnesota Landscape Arboretum, growing successfully in a windy Zone 4.

Tends to be pinker in bud than most, and quite hardy. It's a bushy upright tree, fragrant, and late blooming.

The extraordinary growth rate of this cultivar coupled with its precocious blooming character make it a lucrative item. Moonglow® will grow to 5 ft. and bloom within 2-3 years. Selected and named by Earl Cully, this clone is surprisingly hardy to -33ºF. Lemon-fragrant blooms over a long period in late spring.

A choice cultivar of early-flowering, double pink M. stellata. Compact in form, it flowers precociously and the leaves remain mildew-free throughout the summer. Wonderfully fragrant, frost-resistant flowers on this short, elegant tree means you need one by your own front door.

Hardier than its cousins and not as tall. It grows to only 1-2 ft., has satin foliage, and is more shade tolerant. An elegant low shrub for a spot where it can be left to spread without irrigation.

With its brightly colored, shiny autumn leaves and wide range of adaptivity, especially well suited to wet sites. This is a great landscape tree. Unlike widely-planted Sweetgum, even seedlings of Blackgum are dependable for fall color. Needs pruning when young. These pot-propagated plants ensure transplant success.

Among the largest of the North American oaks, it grows fast and is easy to transplant.
