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.
This variety has a significant advantage over seedlings due to its prominent white stripes on green bark, so much so that the trunk appears mostly white. Twigs and young branches are covered with a waxy white bloom - as on a grape skin. In winter the tree evokes a chalk drawing look in the landscape. Exceptionally hardy.
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.
Betula nigra Dura-Heat® 'BNMTF' (Dura-Heat® River Birch)
Holds its yellow autumn leaves a full month longer than Heritage®. Has glossier leaves, a tighter habit, and better heat tolerance than Heritage® in Zone 9. You already know Earl Cully's Heritage® is a money-making super tree. Try this one for comparison, especially if you're in the Gulf States.
Betula nigra Heritage® 'Cully' (Heritage® River Birch)
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.
Betula nigra Northern Tribute® 'Dickinson' (Northern Tribute® River Birch)
This is proving to be the most adaptable river birch to dry and alkaline soil conditions in addition to be completely hardy in zone 3. So, no die back from winter injury and no iron chlorosis or the mortality that can cause. The parent tree is the largest of this species observed in the upper Northern Plains; it has a proven track record of over 40 years. Ivory colored with striking coppery-bronze exfoliations the bark is appealing year round. Resistant to borers as well.
Most often used as a rootstock for popular cultivars. Seedlings can be effectively used to create a hedge or screen and are favored in Europe for this purpose. Hardy to -38°F in Ohio during the extreme winter of '93-'94.
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.
Among the largest of dogwoods, its best landscape merits are expressed in the Pacific Northwest. Excellent fall color, may repeat bloom. In mild winter areas, it is used as rootstock for exceptionally vigorous C. kousa hybrids.
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.
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.
Native widely distributed in the East. Heat tolerant, tough and having more ornamental character to recommend it than is widely acknowledged. The astringent fruits are most attractive, accented on top with large, persistent calyces. Fruit can be abundant, but isn't usually messy because it persists late into winter, providing a tasty treat for wildlife after the first hard frosts. The deeply furrowed, blocky bark on mature trees is especially handsome when accented by winter snow. Its unobtrusive size and ease of care make this a tree that deserves more attention by designers and landscape firms, and our propagation numbers reflect big recent up-tick in demand.
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.
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.
With all the great ornamental attributes of blackgum, including exceptional fall color and ease of care, this selection allows even more flexibility of location because of its columnar habit. Tupelo Tower™ was selected from a Zone 4 seedling population and is a full zone hardier than other available cultivars.
A graceful, slow growing native tree that tolerates shade and grows to 40 ft. tall. Bark peels in vertical strips. Very easy to grow in the nursery and relatively fast to finish. Pleasing yellow fall color.
Essentially the tree form of witchhazel. It naturally becomes a low-branched tree, typically two-thirds as broad as it is tall. Bark exfoliates on older branches; leaves turn brilliant red, yellow and orange in autumn. With a bit of selective pruning when it's young, but minimal care thereafter, it becomes a medium-sized tree of appealing form. Maroon spring flowers are small, easily missed but attractive, rewarding the curious.
Pest-free and exceptionally drought tolerant small tree (20 ft.), with excellent red, purple, and orange fall color, even in the Deep South. A logical tree for infertile soils or unirrigated urban sites along streets, in parking medians, or under power lines, where it's tough character will ensure its success.
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 x warei 'Birthday Candle' (Birthday Candle Oak)
Guy Sternberg, Starhill Forest Arboretum, introduced this fine oak hybrid in recent years. Tight branch habit, straight stems, and columnar form. Here in Oregon the persistent golden winter foliage contrasts with the typical russet of oak or beech leaves.
Selected at Starhill Forest Arboretum by Guy Sternberg for it's good columnar habit and exceptional fall color. Here in Oregon we have noted it's ability to grow very rapidly but with straight stems, while other columnar selections have the habit of having wavy growth similar to Q. robur fastigiata. Indeed the fall color is a stand out of among oaks for us, with yellows, orange and some red. The retained winter foliage is darker by several shades when compared to other oaks.
Sassafras is aromatic in all its parts. Historically, it has found medicinal uses and was the raw ingredient used to make “root beer”. It surely found its way into “moonshine” for some spicy flavoring. Its foliage is distinctive with 4 different shapes: right and left-handed mitten, un-lobed, and tri-lobed. Difficult to propagate reliably, it is nevertheless a trouble-free native American tree once established in the landscape. Often suckers if it is disturbed. Occurring in groves of small trees, along fence rows, and in abandoned fields in its native range; if it grows on its own in the open it can reach a height of 60 ft. with a 2-3 ft. trunk diameter. Needless to say, trees of this size are now rare and merit protection.
Among the most desirable of all deciduous landscape trees. Camellia-like flowers in early summer. Striking bark patches that resemble pieces of a puzzle. Diminutive mature size, ideal as a small specimen tree. Red, yellow, and orange autumn leaf colors. This taxon is the ideal landscape tree - the complete package. Our strain is originally from the vicinity of Nikko Park in Japan, and has survived the extremely harsh winter lows of the UP in Quinnisec, Michigan. We're talking 35 below zero! Check out their amazing root systems, pot up or plant them out, and make some money.
Narrow, perfectly upright form; mature size 70 ft. x 18 ft. with minimum leaf litter due to its fine-textured foliage. Lends an aristocratic air to the landscape, especially if several specimens are grouped like sentinels along a water course or pond. Chosen as a runner-up in the 2002 Urban Tree of the Year competition held by The Society of Municipal Arborists.
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.
