Vigorous and easy to grow in the nursery, this gives the plant an aggressive tendency, especially in rocky, dry conditions where other trees fail. Accordingly, these are offered strictly for rootstock use. This maple has the remarkable trait of a “universal donor” as a rootstock for many but not all species. We've successfully grafted everything from Acer pentaphyllum to Acer griseum onto it with no sign of long term incompatibility.
Medium-to-large tree of rounded shape. Attractive foliage is sometimes affected by disease; fall color is variable, from yellow to orange mixed with red. The selection 'Autumn Splendor' offers major advantages by comparison: consistency of fall color, disease resistance, and smaller stature.
Carpinus betulus 'Fastigiata' (Pyramidal European Hornbeam)
An excellent ornamental because of its clean foliage, generally, upright growth habit, and adaptability. Branches ascend, but its form is not columnar in outline. It has a wide, round base and typically lacks a central leader.
Carpinus betulus 'Frans Fontaine' (Frans Fontaine European Hornbeam)
Similar to 'Fastigiata', but with slower growth habit and denser foliage. Its narrow columnar form grows to 40 ft. at maturity. The crispy serrated green leaves turn to gold in the fall, an attractive contrast to the smooth, gray bark.
This hardy, medium-sized tree is truly distinctive. Heart-shaped leaves attract interest, changing from translucent bronze in spring, to summer green, to yellow and apricot-orange in autumn. Multi-trunked specimen trees with shaggy bark have eye-catching appeal. Throughout the seasons, it is among the most appealing of any hardy landscape tree. Dr. Mike Dirr names it his personal favorite. These liners are exceptional, with a strong central leader.
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.
This handsome, wide-spreading Chinese tree reaches 30-45 ft. in height. It has a layered, horizontal branch habit, and showy 5-7 in. clusters of small white flowers that precede purple-black fruits in the fall. Taller and more tree-like than its American cousin, Cornus alternifolia.
The intriguing flowers of this Chinese native tree invite closer inspection. Similar to Flowering Dogwood and Chinese Dogwood, the "petals" are actually large white bracts that overshadow the inconspicuous actual flowers. Difficult to propagate and locate in the wholesale trade, Dove Tree is widely adapted and fast-growing to 40 ft. tall. Once established, it makes an strong specimen tree, seldom damaged by ice storms.
Fagus sylvatica 'Dawyck Gold' (Dawyck Golden European Beech)
Tightly upright without pruning. Its moderate growth rate makes it a useful landscape plant. Bright golden spring foliage fades to green, followed by pleasing bronze fall color. Selected in Scotland as a seedling cross of the green 'Dawyck' Columnar Beech and the golden variegated variety 'Zlatia'.
Fagus sylvatica 'Dawyck Purple' (Dawyck Purple European Beech)
A favorite purple beech that holds a beautiful narrow, upright form. Selected in Scotland as a chance seedling cross of the green 'Dawyck' Columnar Beech and a purple-leaf form, it has become a mainstay in the landscaping trade for its consistent dark purple foliage and appealing upright habit.
Fagus sylvatica 'Riversii' (Riversii Purple European Beech)
Deep purple, shiny leaves, upright when young, spreading to form a 60 ft. globe at maturity. Long in cultivation: cemeteries in many Eastern US cities were often planted with this variety, or other purple beeches that have grown to enormous impressive specimens. Fast-growing in the nursery, they make great field plants to bump later into a #15-20 container.
Fagus sylvatica f. purpurea (Copper Beech, Purple Beech)
A relatively inexpensive alternative to more expensive grafted varieties, these beauties offer dark purple leaves in the spring draw customer attention in the garden center. Utilize them as specimens or to make a distinctive hedge. Seed is difficult to procure annually so our supply is hard to predict. So get these when you can, a few years' supply at a time.
Witness to the birth and extinction of countless species over a period of 150 million years, Ginkgo survives to charm us with its unique fan-shaped leaves and butter-yellow fall color. Consider that even after Hiroshima was devastated by nuclear blast, fire and radiation in 1945, at ground zero it was the lone re-generating tree the following spring. Merits wider use: many new grafted male cultivars are becoming very popular. These are un-sexed seedlings, used almost exclusively for grafting.
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.
Everyone's grandma had a walnut table, but the craftsmen who made them are increasingly scarce, and trees of size to cut 16-inch wide boards are too valuable these days to survive much longer on private property unless grandma has her rolling pin handy. Tough, slow-growing American native.
Among the tallest of our native American hardwoods, it shares much in common with Magnolia acuminata. Intriguing cup-shaped flowers of orange, yellow, and green in early summer. Grows fast if planted in deep, moist soil, but it will languish if planted in a dry or compacted area.
Quercus bicolor (Missouri source) (Swamp White Oak (Missouri source))
Flaking bark texture, even on young trees. Although its common name indicates that it prefers moist areas, it is drought tolerant. The silver undersides of the leaves lend contrast to the upper leaf surface, prompting the species name "bicolor". Among the easiest of the oaks to transplant, it is also hardy and has few insect or disease problems.
Quercus Forest Knight® Q. robur x Q. alba 'Tabor' (Forest Knight® Hybrid Oak)
A handsome new selection from our friend of many years, Earl Cully. His judgment is well-respected in the industry. Forest Knight is a great street tree for new neighborhoods due to its leafy, high canopy features. It is broad spreading (to 50 feet) but the central leader is strong so it will develop fantastic symmetry over time.
Named to honor Nicholas Garry of the Hudson Bay Company, this is the climax species of the pre-1850s Willamette Valley oak savannah. We see occasional see remnants of these original trees, some of which measure more than 5 ft. through and exceed 300 yrs. old. These are truly heritage trees, having sheltered and fed the Calapooya Indians, who gathered acorns by the ton and processed them to make thick soup and flatbread.
One of the hardiest evergreen oaks, its natural range is from the Mediterranean to Western Pakistan. The tree becomes huge and creates deep shade with dense pendulous branching and dark foliage. As the tree grows larger, some branch thinning makes for a pleasant, airy canopy on open-growing specimens. Best host for black truffle culture.
Quercus Jordan Street® Q. alba x macrocarpa 'Atwood' (Jordan Street® Hybrid Oak)
With outstanding hybrid vigor, dark green foliage that is highly resistant to powdery mildew and almost perfect branching structure Jordan Street is perfect shade tree. It has shown no sign of damage from wind or ice and is hardy to below -28F and windchill to -86F - wow that is cold.
Quercus macrocarpa (North Dakota source) (Bur Oak (North Dakota))
Native across a broad range in the eastern US, it is consequently variable in leaf form, size and growth rate. Our seedlings are of Missouri source. This patriarch forest tree is best for parks and large, open landscapes.
Quercus macrocarpa (Northeast US) (Bur Oak (Northeast US))
Native across a broad range in the eastern US, it is consequently variable in leaf form, size and growth rate. These seedlings are Pennsylvania source. This patriarch forest tree is best for parks and large, open landscapes.
Widely planted throughout the eastern US because it tolerates wet sites and disturbed, compacted soils. Pin Oak is sometimes seen with chlorotic foliage caused by iron deficiency in high pH soils. In such areas, Quercus ellipsoidalis is a superior landscape choice, better adapted to limestone soils.
Also known as Basket Oak, the wood of this tree splits easily into strips of great strength. In the South it was once used to make hundreds of thousands of baskets for packing cotton from the field. Its utility in bygone generations is now eclipsed by its great ornamental beauty. Performs well even in poor, rocky soil.
Native range is Southwest Europe and northwest Africa, but it is completely at home in warmer regions of North America. Its corky bark can be sustainably harvested every 10 years or so. Frost sensitive, it must be grown in warm climates. A tree of exceptional ornamental beauty for its bark and handsome foliage.
Landscape designers love this clone for its stately pyramidal form. A fast grower with a broad spreading crown, it will get 50+ ft. tall but maintain a dependable central leader. A fast grower, it's much broader than Shawnee Brave.
Ulmus americana 'Princeton' (Princeton American Elm)
Selected almost a century ago by New Jersey nurseryman William Flemer for its aesthetic merit. By stroke of good fortune, 'Princeton' has demonstrated moderate resistance to Dutch elm disease. Typical of this iconic American species in form and hardiness, it is an important part of the American experience, a relic selection from America's urban forest history, still adapted to its future so many generations later.
