A Pacific Northwest native, Vine Maple heralds the arrival of autumn as its colors light up the forest. Best grown in clump form, it lends a pleasing accent to larger trees in a border planting and requires almost no care.
Acer circinatum Three Cheers™ 'HSI2' (Three Cheers™ Upright Vine Maple)
A Heritage Seedlings selection, much more upright and tree-like. The dark green foliage is of normal size and shape, but its silhouette is an attractive flame shape, twice as tall as wide with unusually tight branch angles. If you're pruning wild seedlings into tree form, abandon that tactic to save labor. Upgrade your vine maple list to offer this new native selection and show your customers the benefit of predictable form in a residential landscape. It offers the prospect of uniformity and lower maintenance in a commercial job.
A relatively new introduction from Japan, it has bright yellow stems and shares with other bright yellow or red-stem selections susceptibility to Pseudomonas stem blight if it is fertilized too late in the growing season. Go easy on the nitrogen and protect young grafts indoors for the first few winters until the recent season's growth hardens off.
The outstanding features of this small Asiatic maple are its extreme cold-hardiness and brilliant yellow, red and orange fall color. Not injured by wintertime lows down to -40°F. This is a full 20°F colder than the low temperature limit of other Japanese maples! Here's a fine plant to add some spice to gardens in the upper Midwest. Seed source is northeast China.
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.
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.
A large shrub that spreads from root suckers, it is usually no more than 10 ft. tall. Tolerates deep shade and still flowers reliably. Although its suckering habit and small stature might suggest a tender nature, it is remarkably hardy, tolerating winter lows to -31°F. Rarely found in quantity in the wholesale trade, this is a choice American native to reserve for your best customers.
Widely adapted and tolerant of damp soils, our US native Pawpaw has been under-used as a landscape tree but is attracting substantial attention. This genus is the exclusive food plant for native Zebra Swallowtail butterfly larvae in the East. Nodding purple flowers are unlike those of any other American tree - curious with their three-lobes, pollinated by flies. The perishable fruits have a memorably delicious taste, are nutritious, and resemble the tropical mango. Bold leaves turn a pleasing yellow in autumn. Our seedlings are greenhouse-grown in root-pruning containers for excellent transplant success.
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.
Carpinus caroliniana WI Source (Hardy American Hornbeam, Musclewood)
A seedling strain selected over many years by Mike Yanny of Johnson's Nursery in Menominee Falls, WI. for improved orange-red autumn color. A small-scale (to 30 ft. x 30 ft.) tree with a dense canopy. Its leaf and bark characteristics resemble a small beech tree with fall color. Easy to transplant. Use as rootstock for Firespire™ to assure grafted plants will survive in zones 3-4.
For over 35 years Michael Yanny, Wisconsin, has been selecting and improving his native Musclewood. He started with a few trees that had some fall color and now he releases, with our help, the Wisconsin Red™ strain which has amazing fall color, so much so in fact, if you didn't know better you would suspect it was a different species. Raging reds, oranges and yellow autumn tones set this strain apart from normal seedlings and even his earlier work. Limited supply this year.
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.
Cercis canadensis 'Ace of Hearts' (Ace of Hearts Redbud)
An exceptionally attractive, relatively new introduction from TN. With so many new redbuds in the trade, we have to wonder when they will start to look like re-runs, but this is clearly a fine variety. Smaller in stature (12-15 ft. at maturity) than the species, its foliage is set on its branches with Vegas dealer-like precision. This one will grab your heart.
Cercis canadensis 'Appalachian Red' (Appalachian Red Redbud)
Some plants are described as having red flowers, but the term "red" used here in the cultivar name misinforms those who have not seen it in flower. Many firms list flowers as "fuchsia pink". It's certainly not blood-red like Rosa moyesii, but this selection is a distinctively much brighter pink than seedlings. So it catches your eye - one of our favorites. Its flowers closely match the intense pink color of Prunus campanulata.
Aptly named, its fragrant pink flowers are a delight to the senses. This plant delivers exceptional value in performance for price paid. It is a clean, easily grown plant worthy of a prominent spot where you can appreciate it. Extremely hardy.
With attractive lacey foliage that is very sweetly scented this makes an attractive, colonizing, small shrub that should be planted where it can be seen closely and easily touched to release its fragrance into the air. It has a long history of medicinal uses but is seen less frequently than deserved outside the North East.
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.
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.
Beautiful small American native with tiered branching. Wonderful floral display of white flowers and great fall color. Despite the enormous number of named selections out there, when one sees seedling specimens in the East in cemeteries or parks, there are always plenty of these that elicit, "Someone ought to name that one."
Cornus kousa var. chinensis 'Snow Tower'® (Upright Chinese Dogwood)
It has all the features you've come to expect from Chinese dogwood: excellent white flowers followed by showy fruit, great fall color of orange red and narrower habit - to only 8 ft. wide in twenty five years. Snow Tower could easily be utilized as a street tree with such a habit!
With clean, dark green leaves through summer and large white flowers in abundance, many people are surprised by Mandarin Jewel's bright orange fruit. This color stands out much better against the foliage as compared to the usual red fruit color, more visible from a distance.
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.
Another very fine hybrid from Dr. Orton, this kousa x nuttallii hybrid has stunning pink-red blossoms. One of the top reds on the market. A well branched and freely-flowering tree, it is disease resistant, hardy, and has great red fall color.
A Rutgers selection with huge white flowers, foliage resistant to the leaf diseases that plague seedling flowering dogwoods. Here in Oregon, our stock plants flower for a month starting in early to mid-May. Its exceptional vigor can result in too-leggy growth, even with routine fertilizer use. Manage nitrogen application conservatively.
Of refined, delicate appearance year-long, this woodland shrub from Japan makes a great substitute for witchhazel in smaller gardens. It slowly mounds up, becoming more broad than tall, and is easily maintained. Primrose yellow flowers cover the branches in early spring. Prefers moist, partially shaded borders and open woods, but tolerates a sunny spot fine: it just grows more slowly in full sun.
A choice shrub, rare in the wholesale trade because it is so very compact, no more than 3 feet in twenty years, producing almost no cuttings. Large, snow-white flowers and deep green foliage which turns brilliant red in autumn.
Fothergilla x intermedia 'Mt. Airy' (Mt. Airy Dwarf Fothergilla)
A select American native, 'Mt. Airy' merits wider use as compared to its close relatives, the witchhazels, which are much larger in mature stature. Exhibits excellent hardiness, attractive summer foliage and spectacular autumn color. The white bottlebrush flowers are borne in showy abundance during April/May.
Always sought after, this uncommon tree is celebrated because of its legendary origin in horticulture as well as its role as an extraordinary landscape plant. Camellia-like flowers are borne from early autumn until frost. Brilliant, shiny autumn foliage-a plant for your connoisseur clients.
A Pacific Northwest forest shrub, Salal's landscape potential is often overlooked. Shiny, long-lasting leaves, showy flowers and edible fruit. Low-maintenance landscape border. Prune low every 3-5 years.
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.
Most often used as a rootstock for selected cultivars. This native American shrub can grow to 20 ft. with equal spread. Prefers moist soils, but full sun in the landscape encourages more compact growth. Trim branches just before the plant blooms to force indoor flowers.
Due to its multi-season appeal, this multi-stemmed tree, introduced from China only in 1980, is finally starting to gain followers. Covered with large clusters of white flowers in mid summer, in late summer and fall it displays great masses of pink-red seeds. Finally, the winter season highlights its shaggy bark - the color of soft beach sand. It does require shaping to highlight its normally "stemmy" form - a central leader formed early helps to make it a highly marketable tree, but it cannot be reshaped if neglected when small.
